High beams are really for rural roads with very little traffic. If there are at least three lanes of traffic in one direction[1] and enough traffic that a car in front was able to see the collision in their rear view mirror, high beams are not advised.

Using them in this situation will cause major glare from mirrors of the drivers in front, and possibly for the drivers in the opposing direction.
