Motor vehicle tires can become permanently damaged if a flat occurs in the traffic lane and the driver pulls over onto the shoulder with the flat tire passing over the rumble strip. This may cause the flat tire's sidewalls to be crushed or abraded between the metal wheel rim and rumble strip high-points.

An example of extensive cracking in rumble strips due to frost jacking on Interstate Highway 81 north of Syracuse. These parallel cracks were sealed. There were other sections with grass and weeds growing up through the rumble strip cracks Generally, deterioration of the shoulder asphalt pavement due to rumble strip installation is not a problem. However, if the sub-grade under the CSRS is poorly compacted or has poor drainage characteristics; or the gravel shoulder has eroded, crack(s) may form in the CSRS.

Many of the first installations (Route 46 in Bergen County and Passaic County, for instance) were much shorter than the heights discussed here, typically about two feet tall. Some dividers on county or local roads may have been lower than that since they replaced a raised concrete rumble strip that would dissuade, but not prevent, traffic crossing from one lane to another. Even Route 46 had the rumble strip in many places before gradually, the higher barrier was installed. These lower dividers are visible in old photographs.

Moist traction sand tends to cake together or freezes, and is not easily dislodged by truck traffic. This is problematic on low-volume highways with frequent deicing, and can significantly reduce the effectiveness of rumble strips in winter months. When rumble strips are installed on a very narrow paved shoulder, sometimes sand and gravel can fill the rumble strip which is usually a problem in the winter and early spring. If the snow-cover is substantial, then the shoulder (including the rumble strip) is usually partially snow-covered as the snowplow's wing-blade doesn't clear the entire shoulder.

The former SR 141 was absorbed into US 12, while SR 121 was re-used for another highway in Thurston County. Traffic congestion on SR 141 during peak months has risen due to an increase in the number of visitors to recreational facilities on the corridor, requiring lowered speed limits to prevent vehicle–pedestrian collisions. A shoulder rumble strip on the highway was removed and replaced with a fog stripe during a chip sealing project in 2014, causing local residents and recreational users to protest. In response, WSDOT installed a rumble strip along the shoulder line to improve safety for pedestrians and bicyclists using SR 141.

A line of red cats' eyes is also used, and is placed to the side of the line. On many modern non-motorway roads, a hard strip is provided. These are usually wide, and are bounded by thinner solid white lines, and often without a rumble strip.

These beads provide initial retroreflection. As the marking wears during use and the initial beads are lost, the beads mixed with the binder are uncovered, providing long term retroreflectivity. These can be made exceptionally thick to produce a rumble strip effect. The thermoplastic marking coating sets quickly.

Vehicles going off the road usually collide with the shoulder snow bank or go into a snow-filled ditch which reduces the possibility of serious damage and injury. In these situations, the rumble strip effectiveness can be negated but the crash implications are mitigated by the snow bank.

The argument that rumble strips help protect cyclists is moot, as inattentive drivers' vehicles generally pass entirely over the rumble strip before recovery (if any). Other related FHWA guidelines are: "Rumble strips should not normally be used in urban or suburban areas or along roadways where prevailing speeds are less than ." and "All responsible agencies should work in cooperation with bicycle groups, enforcement agencies, emergency groups and other roadway users, to develop policies, design standards and implementation techniques that address the safety and operational needs of all roadway users." and "To provide a clear area beyond the rumble strip for bicycle travel, highway maintenance agencies should periodically sweep shoulders along identified bicycle routes of high bicycle usage." In the United States, the 1999 American Association of State Highway and Transportation Officials (AASHTO) Guide for the Development of Bicycle Facilities recommends minimum standards for road shoulders receiving rumble strips to accommodate all users of the roadway and make best use of funds. In New Jersey, a centerline rumble strip was placed in the vicinity of the D&R; Canal without a permit from the Delaware & Raritan Canal Commission in violation of state law.

Normally, salt would make its way off the pavement onto the gravel shoulder and into the soil, however, rumble strips will retain and create a salt lick on the road surface. Loose rock salt in the rumble strip subjected to evaporating moisture will cake and accumulate and is not easily dislodged by truck traffic.

A typical rural American freeway (Interstate 5 in the Central Valley of California). The yellow line is on the left, the dashed white line in the middle, and the solid white line on the right. The rumble strip is to the left of the yellow line. Painted lane markings vary widely from country to country.

Traction sand filled shoulder rumble strip. The sand is "cemented" in-place and is not easily removed by truck traffic. Climate is another factor that affects the success of a rumble strips installation. If they are installed in a northern climate, they may be filled or partially filled with a deicing salt and traction sand mixture.

Rumble strips were first implemented on the Garden State Parkway in New Jersey in 1952. Initially, shoulder rumble strip installation focused on freeways using rolled-in rumble strips of different designs using a modified roller on a pavement rolling machines. Later, paving contractors modified pavement rolling machines to mill rumble strips into existing hardened asphalt pavement. Specifically designed commercially available machines followed.

Rumble strip installation is widespread, and in some cases controversial. Residents near urban freeways complain of noise at night as vehicles change lanes; or when vehicles strike the transverse rumble strips. The encroachment of shoulder rumble strips onto highways with narrow shoulders may create a hazard for cyclists. US and Canadian guidelines have minimum standards for installation on known cycling routes.

This "slowly drift to the right" scenario applies to jurisdictions with right-hand traffic, so in jurisdictions with left-hand traffic it would be a "slowly drift to the left" scenario. This phenomenon implies that a sleeping driver often does not react and begin to recover, until all four wheels have struck a rumble strip; if the paved shoulder is narrower than the width of the vehicle wheel track, a rumble strip may not prevent a sleeping driver from going off the road. On a single-lane highway, an overreacting driver has less room to regain control, which may exacerbate their initial overreaction after striking the strips, resulting in a roll-over or head-on collision. A crash investigating officer stated: "It's consistent with someone who falls asleep or overreacts to the rumble strips", which implied that this was not the first time the officer has witnessed this situation.

The study also stated that unprevented crash severity may worsen, and the overall results were inconclusive. The study suggested that the differences in rumble strip-related crashes between Interstate highways and primary highways were due to the primaries having smaller shoulders than Interstates. Secondary highways are single-lane undivided highways, and CSRS would be expected to be less effective than on primary highways. The most serious problem would be an increase in crash severity.

A 2007 Canadian study suggested that unsafe drivers are habitual, and that unsafe driving is increasing. A 2009 Canadian study indicated that, after a steady decline, drinking and driving has been on the increase since 2004. These support the migration and behavioral adaptation rumble strip concerns. A safe driver population has more potential for negative behavior adaptation than an extreme unsafe driver population; whereas, an extreme unsafe driver population has more potential for positive behavior adaptation than a safe driver population.

The first production lane departure warning system in Europe was developed by the United States company Iteris for Mercedes Actros commercial trucks. The system debuted in 2000, and is now available on many new cars, SUV’s and trucks. In 2002, the Iteris system became available on Freightliner Trucks' North American vehicles. In both these systems, the driver is warned of unintentional lane departures by an audible rumble strip sound generated on the side of the vehicle drifting out of the lane.

A concern about highways with narrow paved shoulders is the condition of the adjacent gravel shoulder. Sometimes, the paved and gravel shoulders are combined as the "recovery zone" beyond the rumble strip. However, if the gravel is loose, soft, non-level, eroded, or there is an "edge-drop" from the pavement to the gravel, then the gravel shoulder portion will be ineffective for recovery, especially at highway speeds. When a vehicle's tires sink into a soft shoulder, thus compromising vehicle handling, it is known as "vehicle tripping".

The caves are meant to break the routine, providing a refreshing view and allowing drivers to take a short rest. The caverns are also used as turnaround points and for break areas to help lift claustrophobia during a 20-minute drive through the tunnel. In the tunnel, there is a sign on every kilometer indicating how many kilometers have already been covered, and also how many kilometers there are still to go. To keep drivers from being inattentive or falling asleep, each lane is supplied with a loud rumble strip towards the centre.

The southern median has a bike path, part of the Brooklyn- Queens Greenway which runs south from the western end through Prospect Park to Ocean Parkway and east from the eastern end through Forest Park. The southern median's bike path is separated from the pedestrian path by way of a "rumble strip" between the pedestrian and bike lanes. The northern median is for pedestrians only. Many trees along the parkway bear plaques commemorating soldiers fallen in World War I. Today, the trees come from about 25 different species.

A roundabout was constructed in southern Duvall to replace the unsignalized intersection at Northeast 124th Street in 2004, the first to be built on a rural highway in Western Washington, and received favorable feedback from local residents. WSDOT completed construction of a second roundabout in 2008 at the highway's southern terminus with SR 202 in Fall City, costing $4 million. A 2004 study of potential improvements to SR 203 also suggested the addition of a rumble strip in the road's centerline, along with hard landscaping to force motorists to slow down when entering populated areas.

Deicing salt-filled and stained rumble strip. The rock salt has been "cemented" in place Wildlife-vehicle collisions can be a significant problem when large animals are involved such as moose, elk, and deer, which can cause serious vehicle damage, injury, and fatalities.Update of Data Sources on Collisions Involving Motor Vehicles and Large Animals in Canada, Transport Canada, June 2006 Separate studies in New Hampshire (US) and Quebec (Canada), of radio-collared moose found that home ranges were associated with salt licks formed by road salt runoff. These roadside salt licks were thought to increase moose-vehicle collisions.

A2 at Leyton Cross, United Kingdom. Full width hard shoulders are usually provided only on motorways and are usually wide, but there are exceptions. Some motorways do not have hard shoulders at all (for example the A57(M) and many smart motorways where the hard shoulder has been converted into a running lane) and there are a small number of dual carriageway A-roads which do possess hard shoulders (for example, parts of the A1, A2 and A27). Hard shoulders are always marked with a reflectorized solid white line which is wide and is provided with a rumble strip.

While the session saw no major incidents, Ralf Schumacher entered the gravel traps at the two of the track's corners. After the warm-up session, Montoya predicted several drivers would run wide on a rumble strip located to the outside of the circuit, which extended from turn one to the first portion of the straight driving towards turn two, to increase the top speed of their cars. Ron Dennis, the team principal of McLaren, argued Ferrari should allow their drivers to race each other without the imposition of team orders favouring one driver over the other as had happened in the 2001 race.

Given behavior adaptation and migration, the current rigorous Interstate effectiveness of 14%, and CLRS on single-lane highways effectiveness of 14% could be over-estimations of the actual "big-picture" reduction. In certain situations, such as an engaging single-lane highways that typically have narrow shoulders, high precipitation, in a northern climate with frequent freeze-thaw cycles, rumble strip effectiveness may be negative. As before-and-after studies become broader and more sophisticated, it appears the reduction estimates for both CSRS and CRS are less impressive. This may be due to the initial installations were on highways that had been identified as having very high accident rates due to inattention.

In 2010, Reno County planned to remove rumble strips from a roundabout after residents complained about excessive noise levels.Rumble Strips Near Roundabout to be Removed, hutchnews.com, 2/3/2010 The Transportation Association of Canada and US FHWA guidelines basically specify that a width of of clear paved shoulder between the outside of the rumble strip and the edge of pavement is adequate to provide cyclists with a clear travel path. However, in situations of parked vehicle on the shoulder, debris on the shoulder, or downhill sections even with the clear path requirement, rumble strips present a significant hazard particularly if the pavement is wet.

When the Bergen Mall was first opened in Paramus, these rumble strip dividers were extensively used on the roadway (Forest Avenue) that separated the grocery stores from the mall proper. The design of the Jersey barrier was specifically intended to minimize damage in incidental accidents and reduce the likelihood of a car crossing into oncoming lanes in the event of a collision. In common shallow-angle hits, sheet-metal damage is minimized by allowing the vehicle tires to ride up on the lower sloped face. Head-on vehicle collisions are minimized by gradually lifting the vehicle and pivoting it away from oncoming vehicles and back into traffic heading in its original direction.

Numerous US and Canadian cycling associations have complained about encroachment of rumble strips.Bicycle Colorado One club even launched a lawsuit to have them paved over, although the suit was dismissed for lack of standing. A 2005 Quebec study concluded: "Based on the results of the analyses, it was not possible to recommend a type of rumble strip that would provide sufficient warning to drivers who encroach on the shoulder while remaining safe for cyclists who ride over it."Testing and Evaluation of Rumble Strips Separating Traffic Lanes and Bicycle Lanes on the Shoulder Roadway, Transports du Québec A 2003 Montana study stated that bicyclists cannot operate on shoulders with rumble strips and that shoulders would have to be swept as needed.

The North Luzon Expressway's raised plastic transverse rumble strips approaching Balintawak Toll Barrier, Philippines Rumble strips (also known as sleeper lines or alert strips) are a road safety feature to alert inattentive drivers of potential danger, by causing a tactile vibration and audible rumbling transmitted through the wheels into the vehicle interior. A rumble strip is applied along the direction of travel following an edgeline or centerline, to alert drivers when they drift from their lane. Rumble strips may also be installed in a series across the direction of travel, to warn drivers of a stop or slowdown ahead, or of an approaching danger spot. In favorable circumstances, rumble strips are effective (and cost-effective) at reducing accidents due to inattention.
