Brakes

f
Make it a habit to check the operation of your
brakes before driving.
Keep in mind that the braking distance increases
very rapidly as the speed increases. At 60 mph
(100 km/h), for example, it is not twice but four
times longer than 30 mph (50 km/h). Tire traction
is also less effective when the roads are wet or
slippery.
f
Therefore, always maintain a safe distance
from the car in front of you.
