Driving SafelyPregunta 56 de 60
What is the safest way to brake in a combination vehicle to avoid a skid?
a.Slam the brakes to stop quickly
b.Pump the brakes rapidly at all times
c.Only use the trailer hand valve to stop
d.Brake early and smoothly, keeping the vehicle straight, so the wheels keep traction
Explicación
You should brake early, smoothly, and while the vehicle is as straight as possible so the wheels keep traction and the trailer does not swing. Sudden or hard braking, especially in a turn, can lock the wheels and cause a jackknife. Leaving extra space lets you brake gradually.
