Driving SafelyCâu 59 / 60
Why should you keep a steady, moderate speed rather than speeding up and slowing down often in a tanker?
a.It uses more fuel to keep a steady speed
b.Frequent speed changes create repeated surge that can destabilize the vehicle
c.Steady speed is illegal in work zones
d.Speed changes have no effect on liquid cargo
Giải thích
Every time you accelerate or brake, the liquid surges, so frequent speed changes keep the cargo in motion and reduce stability. A steady, moderate speed lets the liquid settle and keeps the vehicle more controllable. Smooth, consistent driving is safer in a tank vehicle.
