Driving Safely第 55 / 60 题
How does liquid surge affect stopping a tank vehicle at a traffic light?
a.It can push the stopped vehicle forward into the intersection
b.It makes the brakes work twice as fast
c.It has no effect once the vehicle is stopped
d.It automatically holds the vehicle in place
解析
When you brake to a stop, the liquid surges forward and can shove the vehicle ahead, sometimes into the intersection. This is especially strong in smooth bore tanks. Leaving extra stopping distance and stopping a bit early helps you account for this forward push.
