A surface friction tester, used to measure road slipperiness. Road slipperiness is a condition of low skid resistance due to insufficient road friction. It is a result of snow, ice, water, loose material and the texture of the road surface on the traction produced by the wheels of a vehicle.
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]
Unfortunately, these cold temperatures can affect the mechanics of your car, from low tire pressure to dead batteries. Here are a few pointers to help keep your car functioning as the temperatures ...
Since heat in the tires from driving can impact the temperature a lot, accurate readings can only be obtained when the tires are cold - that is at least three hours after the vehicle has been driven or driven less than 1 km (1/2 mi) since cold - tire pressures will not then be higher because of operating heat.

General Motors on Wednesday said it is recalling nearly 462,000 diesel-engine SUVs and pickup trucks in the U.S. because of a faulty transmission control valve that may fail and cause the rear ...
The U.S. government's highway safety agency is investigating complaints that engines can fail on as many as 1.4 million Honda and Acura vehicles. The probe by the National Highway Traffic Safety ...
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.
The precipitation can be in the form of rain, sleet or a mixture of wet weather conditions that have saturated the ground saturated deep down. The severity of the cracking of the soil depends on ...
