Final answer:
In the absence of ABS brakes, use threshold braking in an emergency stop situation by applying steady pressure up to the point just before the wheels lock, then releasing slightly. It allows maximum braking efficiency and vehicle control. Weigh risks when considering emergency actions against traffic laws.
Step-by-step explanation:
To stop in an emergency situation when your car does not have ABS brakes, you should use the technique known as threshold braking. This involves applying steady pressure on the brake pedal up to the point just before the wheels lock, then easing off slightly to prevent the wheels from skidding. It's a method of gaining maximum braking efficiency without the assistance of ABS. Remember to steer smoothly to maintain control of the vehicle while braking. In a situation where you must stop urgently and safely, such as when you're transporting a pregnant woman in active labor to the hospital, knowing and effectively using threshold braking can be incredibly important. However, always ensure to weigh the risk of breaking traffic laws against the urgency of the medical situation, and proceed with the utmost caution.
