RED!
RED!
You are going the wrong way. White means correct direction, red means opposite direction (wrong way), blue means a fire hydrant near.
Double solid red lines are caused by reflectors in the roadway - those facing oncoming traffic are amber or white, and those facing the opposite direction are red. The double red lines indicate that you are driving on the wrong side of the road.

Red
They mark the edge of the safe area, keep clear of them. In the UK red reflectors are always shown to the rear of a vehicle, never to the front, therefore they mean you are approaching the rear of car, lorry, bike etc.
Apparently you need some kind of reflectors on your plate. I was told this by a state trooper but received no ticket. I picked some up local for $1
Reflectors can be white, red, blue, green, yellow, or orange. There may be others as well.
