bear trap(redirected from a bear trap)
A place where a police officer waits, often in hiding, to catch drivers that are speeding. Also called a "speed trap." Likely related to highway patrol officers being called "bear," a possible reference to Smokey the Bear (a cartoon character who wears a hat similar to those sometimes worn by the highway patrol). Ugh, I got a speeding ticket today, thanks to a bear trap.
