In the early morning of March 7, a car collided with another truck that broke down due to rainy and foggy weather on the Beijing-Shanghai Expressway. As we all know, when a car brakes,
60km/h= 16.7m/s，
x 1 = vt = 16.7×0.6m = 10.02m，
The acceleration after braking is a = FM = 0.8 MGM = 8m/S2,
Then the braking displacement is x2 = V22A =16.7216m =17.43m,
Because x = x1+x2 =10.02+17.43m = 27.45m < 37m, the car did not violate the regulations.
Answer: the car didn't violate the rules and speed limit.
