In way of lighting I don't have any, that is why I'm asking so I would know about what I would need in way of lighting. The structure of the scene is:
One truck: it's the vehicle that will cause the wreck
The couple (Characters in the film) are walking down the road a drunk driver comes and hits the female killing her. The driver then wrecks on the other side of the road.
Night shot: Two police cars will give the effect of the wreck, they will give off the police lights flashing. So they will have their car lights on so that will help out with some lighting.
I can have other cars OS to give more light but I still run into the grain.
