Question

1. if you lock the brakes when braking suddenly, you *

avoid losing traction.
lose steering ability.
gain speed slightly.
gain steering ability.

Explanation:

When brakes are locked during sudden braking, the wheels stop rotating and skid. This causes the vehicle to lose the ability to be steered as the normal traction - based steering mechanism is disrupted. Losing traction is actually what happens when brakes are locked, not avoided. And locking brakes does not cause a gain in speed or steering ability.

Answer:

lose steering ability.
