Roadway noise is the collective sound energy emanating from motor vehicles. It consists chiefly of road surface, tire, engine/transmission, aerodynamic, and braking elements. Noise of rolling tires driving on pavement is found to be the biggest contributor of highway noise and increases with higher vehicle speeds. [1] [2] [3]
Bernard told investigators that he was accelerating to get past a merging truck when the accelerator pedal jammed into the floor mat and remained there when he took his foot off the pedal. Bernard was able to slow the car down to 50–60 mph (80–97 km/h) with the brakes, but was only able to bring the car to a complete stop after putting the ...
A tire-pressure monitoring system (TPMS) monitors the air pressure inside the pneumatic tires on vehicles. [1] A TPMS reports real-time tire-pressure information to the driver, using either a gauge, a pictogram display, or a simple low-pressure warning light. TPMS can be divided into two different types – direct (dTPMS) and indirect (iTPMS).
Cold inflation pressure is the inflation pressure of tires as measured before a car is driven and the tires warmed up. Recommended cold inflation pressure is displayed in the owner's manual and on the Tire Information Placard attached to the vehicle door edge , pillar , glovebox door or fuel filler flap .
Rain grooved road that can cause groove wander Groove wander , similar to tramlining , is a lateral force acting on a vehicle's wheel resulting from the combination of rain grooves (grooves cut into roads to mitigate hydroplaning in light rain conditions) and contoured deformations in the road surface upon which the wheel runs.
Skid marks from aircraft tires on a runway. A skid mark is the visible mark left by any solid which moves against another, and is an important aspect of trace evidence analysis in forensic science and forensic engineering. Skid marks caused by tires on roads occur when a vehicle wheel stops rolling and slides or spins on the surface of the road.

As a result of increased sales of full electric vehicle and hybrid electric vehicles in several countries, some members of the blind community have raised concerns about the noise reduction when those vehicles operate in all-electric mode, as blind people or the visually impaired consider the noise of combustion engines a helpful aid while crossing streets and think quiet hybrids could pose an ...
