In Nevada, two cars approach an intersection at night time and none of the traffic lights are working. Both cars enter the intersection without stopping and collide. One car hits the other broadside on the passenger side. When speaking to the police, the driver who was hit by the car which was coming from the right said that they came to a full stop before entering the intersection. The driver coming from the right told the police it wasn't possible to stop since no features of the intersection could be distinguished, and wound up getting the only ticket issued by the police.
The ticketed driver examined the dash cam video upon returning home which conclusively proves the other driver did not stop and therefore was lying to the police. The dash cam was retrieved right after the accident and the driver did not volunteer information about the dash cam and was not asked any questions about the presence of any dash cam.
The police did not suspect anyone of impaired driving but gave sobriety tests as part of procedure. The sobriety test had two parts, and the driver who told the truth had a little trouble with the balance portion (presumably from the stress of the ordeal together with aging (57 years old) and natural clumsiness), despite having had not even one drop to drink. After the test the driver asked to take a breathalyzer but the police said they don't use them due to policy.
Will the video make any difference in the case of the liar or help the truthful driver in court despite having less than perfect balance?
