(If this appears correctly) it should be ÂµA but it's quicker to type uA. Answer: UA stands for Urine Analysis.. When you pee in a cup and the doctors take it and analyze it to see if you or whoever has done any drugs or drank any alcohol in the past two weeks. Microamperes. The u is the closest letter many computer keyboards have to the Greek mu symbol.
Do not blind other drivers with your high beam headlights. Dim your lights by switching to low beams before you are 500 feet from a vehicle coming toward you. If you are following another vehicle, change to low beams when you get closer than 300 feet. Use your high beams whenever possible as long as it is not illegal (i.e., in open country when other cars are not near or on dark city streets when no other traffic would be affected by your high beams).
You should never drive so fast that you are unable to stop within the distance that you can clearly see on the road ahead of you by the light of your vehicleâs head lamps. For most vehicles this distance is no more than 350 feet when the headlights are on high beam.
