If a car moves too fast on a banked road, the centripetal force required to keep the car moving in a circular path may exceed the maximum frictional force between the tires and the road. This can cause the car to skid or slide out of control.
On the other hand, if a car moves too slow on a banked road, the centripetal force required to keep the car moving in a circular path may be less than the maximum frictional force between the tires and the road. This can cause the car to slip down the banked road or not make it around the curve.
In both cases, the forces acting on the car include the gravitational force pulling the car downward, the normal force exerted by the road on the car perpendicular to the road surface, and the frictional force between the tires and the road. The centripetal force required to keep the car moving in a circular path is provided by the frictional force between the tires and the road.
Therefore, it is important for a car to maintain an appropriate speed on a banked road to ensure that the centripetal force required for the turn is balanced by the frictional force between the tires and the road.

If a car moves too fast on a banked road:
- Centripetal force (Fc) is insufficient: The Fc required to keep the car in the curve is greater than the force provided by the banking of the road.
- Outward centrifugal force (Fc') increases: The car experiences a stronger outward force due to its higher velocity.
- Result: The car tends to move away from the center of the curve and may skid or slide outwards.
If a car moves too slow on a banked road:
- Centripetal force (Fc) is excessive: The Fc provided by the banking is greater than the force required due to the car's slow speed.
- Inward centrifugal force (Fc') decreases: The car experiences a weaker outward force due to its lower velocity.
- Result: The car tends to move towards the center of the curve and may slide or tip inwards.
Other consequences:
- Tire traction: Excessive speed or slow speed can reduce tire traction, affecting handling and braking.
- Vehicle stability: The imbalance between Fc and Fc' can lead to vehicle instability and potential rollovers.
- Passenger comfort: Moving too fast or too slow on a banked road can create discomfort for passengers due to excessive lateral forces.
Safe driving on banked roads:
To drive safely on banked roads, it is important to adjust speed to the degree of banking and road conditions. Maintaining a constant and appropriate speed helps balance the forces acting on the car and ensures stability.
