How does liquid surge affect a vehicle going downhill?
a.It has no effect on downhill driving
b.The surge pushes the vehicle forward faster and makes it harder to control speed
c.It helps the vehicle slow down
d.It only affects the vehicle when going uphill
Explanation
When going downhill, liquid surge pushes the vehicle forward, adding to the force of gravity pulling the vehicle downhill. This makes it harder to control speed and increases stopping distance. Tanker drivers should use a lower gear and start downhill at a reduced speed.
