A solid yellow line means you may not pass another vehicle as you near the tracks. Crossbuck signs are posted at most tracks. The sign will indicate if there is more than one track. Flashing lights always mean a train is near. Always stop when the lights begin to flash.
Some crossings also have gates.
Always stop when the gates begin to lower. It is against the law to drive through, around or under these gates. Drive as though you expect a train on any track at any time. More than one train may be on the tracks. After one train has passed, always look for a second train on another track before proceeding.
