means a roadside hotel designed for motorists, typically with rooms opening directly onto a parking lot.

from A blend word, born in 1920s America: "motor" + "hotel," coined as cars filled the highways and travelers needed somewhere to stop for the night without venturing into a city. The first is said to be the Milestone Mo-Tel in San Luis Obispo, California (1925), whose owner reportedly mashed the two words together for his sign — and the portmanteau stuck to the whole roadside breed that followed.
