The amber gambler sped through the intersection just before the light turned red.
amber gambler
idiomA driver of a road vehicle who accelerates when the traffic lights change from green to amber (instead of stopping, as required by law), gambling that no vehicle will cross his or her path; a driver who starts off when the traffic lights show red and amber together, but not yet green.
You should always wait for the light to turn green, as an amber gambler might try to rush through the crossing.
Despite the heavy rain and poor visibility, the reckless amber gambler accelerated aggressively, narrowly avoiding a collision with a pedestrian.
