Answer:braking
Step-by-step explanation:
Large vehicles as compared to small vehicles require long braking distance, otherwise, it could topple the heavy vehicles. Heavy vehicles provide high torque thus it is used to carry heavy loads.
They run at relatively low speed as compared to the light vehicles as they are slow to accelerate and thus require long braking distance as Momentum associated with them is very high.
If sudden brakes are applied it may cause the vehicle to skid and flip over it due to the presence of large momentum.
