"It's clear now. The truck's brake marks form an S-shape. It was originally traveling in the middle lane, but it seems to have swerved, braking from the middle to the right, then turning towards the left. The total brake distance is 34 meters."
"As for the police car, the brake marks, from far to near, are in a straight line, with a braking distance of 11.7 meters. The residue is particularly deep. Mr. Zhao infers that the speeds of the two vehicles were similar, but it seems the truck was attempting to avoid something."
Mr. Zhao pursed his lips tightly and glanced at Zou Jialong.
"This judgment is not accurate. At a speed of 60 km/h, the braking distance is around 14 meters, and the reaction distance is about 5 meters, so the total braking distance is 19 meters. At night, reaction speeds are slower, so the lighter color in the latter part of the 11.7 meters indicates that the police car's speed was between 50 and 60 km/h.
