Morphology
The meaning 'a device that measures and displays speed' is directly and transparently derived from combining 'speed' (measure of how fast something moves) with 'indicator' (an instrument that signals or displays a state). This noun–noun compounding pattern is regular in English and mirrors constructions in many other languages, so a B1 learner who knows both constituents would readily infer the MWE's meaning.
Etymology
Speed indicator is a compound name that links speed (how fast something moves) and indicator (something that shows). So, a speed indicator is a device that 'measures and shows' how fast a vehicle is going.
