Morphology
The meaning 'a place where drivers are caught for speeding' is directly and compositionally derived from 'speed' (how fast something moves) + 'trap' (a device or setup to catch). This noun‑noun compound follows a common English pattern ('trap for X') and is cross‑linguistically intuitive, so a B1 learner who knows both words should be able to infer the MWE's meaning.
Etymology
Speed trap paints a simple picture: police hide by the road and wait to catch drivers going over the speed limit, like people caught in a trap. So it now means 'a place where police hide to catch and ticket drivers who are speeding'.
