Speed Limits and Distance Control Flashcards

What is the typical minimum speed required on expressways in the Philippines?

Answer: 60 kph

Most Philippine expressways require a minimum speed of 60 kph to maintain safe traffic flow and prevent hazards from very slow vehicles.

Tailgating is dangerous primarily because it:

Answer: Reduces your reaction and braking time if the vehicle ahead stops suddenly

Following too closely leaves insufficient space to stop if the vehicle ahead brakes suddenly, making rear-end collisions highly likely.

Compared to stopping at 30 kph, stopping at 60 kph requires approximately:

Answer: Four times the distance

Since stopping distance increases with the square of speed, doubling speed from 30 to 60 kph requires approximately four times the stopping distance.

The total stopping distance of a vehicle consists of:

Answer: Reaction distance plus braking distance

Total stopping distance includes reaction distance (time to perceive and apply brakes) plus braking distance (time for brakes to halt the vehicle).

What is a safe speed to drive in a parking lot or heavily congested area?

Answer: 10 kph or less

Parking lots and congested areas have pedestrians, children, and reversing vehicles, so driving at 10 kph or less allows safe stopping at any moment.

Which factor most significantly affects the required safe following distance?

Answer: Your vehicle's current speed

Speed is the most critical factor, as higher speeds require much greater distance and time to stop safely.

Under what circumstance is it legal to exceed the posted speed limit?

Answer: It is never legal to exceed the posted speed limit

The posted speed limit is a legal maximum and cannot be exceeded regardless of personal urgency, traffic behavior, or any other reason.
