Final answer:
The technique the driver should use to stop quickly without ABS is threshold braking.
Step-by-step explanation:
If a vehicle does not have ABS (Anti-lock Braking System), the driver should use the technique of threshold braking to stop quickly.
Threshold braking is a method where the driver applies and releases the brakes right up to the point of wheel lock, allowing the tires to maintain maximum grip with the road surface. By doing this, the driver can effectively control the braking force and reduce the stopping distance of the vehicle.
