Regarding tire trace analysis, Qin Yong hasn't dealt with it much, but he has encountered it in past cases.
However, for Zhang Yongzhi, the captain of the traffic police team, he's seen it many times.
Tire trace analysis has always been a strong suit for the traffic police team.
In general traffic accident scenes, it's relatively easy to distinguish responsibility.
Who is primarily responsible, who is secondarily responsible, experienced traffic officers can tell with just a glance.
At worst, if both parties are at fault, both might share equal punishment.
As for retrieving surveillance footage, well...
If there are no major casualties, don't count on it.
No matter how luxurious the car is, it's usually resolved on the spot.
Moreover, not all accidents occur at places with cameras.
Therefore, tire trace analysis becomes an important means to determine traffic responsibility.
