Paved roads with good maintenance and proper drainage are generally considered the safest type of road surface for everyday driving. Asphalt and concrete surfaces offer good traction and visibility in various weather conditions, reducing the risk of accidents.
Coefficient of friction on raod and a tire varies depending on the condition of the road and tyre Wet Road: 0.4 Dry Road: 0.7 This is the average coeffecient for these conditions again it can vary
The frictional force between a tire and a road is necessary for the tire to grip the road surface and provide traction for the vehicle to move. This force is influenced by factors such as the texture of the road surface, the materials of the tire and road, and the weight pressing down on the tire. A higher frictional force allows for better control and stability of the vehicle.
Static friction causes a car tire to turn on the road. This friction occurs when the tire grips the road surface and prevents slipping. The friction between the tire and the road allows the car to accelerate, decelerate, and turn.
A pit type weighbridge is mounted in a pit. It takes more work to install. The weighing surface is level with the road. A pitless type weighbridge is mounted on the surface. The weighing surface is mounted with a ramp leading up a short distance.
After rain, the road surface dries through a combination of evaporation and drainage. The heat from the sun helps to evaporate the water on the road, while any excess water is drained away through the road's surface or drainage systems. The rate of drying depends on factors like temperature, humidity, wind speed, and the porosity of the road surface.

When cycling on the road, it is safest to ride with traffic, not against it.
