-Check tire pressure and tread often
-Replace worn shock absorbers
-Good traction on dry, flat road
-reduced traction on gravel, snow, ice, leaves, sand and oil (REDUCE SPEED)
1. Sharpness of curve- the sharper the curve, the more traction your tires need to grip the road in order to overcome inertia.
2. Speed and weight of vehicle-The momentum of your vehicle increases speed. The faster you go, the more traction you need to overcome momentum. If you go to fast, your vehicle might not be able to make the turn.
