How often do companies inspect their tourist vehicles?

SLTDA regulations say registered tourist vehicles go through strict mechanical and aesthetic inspections every year to keep their tourism permits. Also, many high-end agencies require internal fleet checks between every tour, before each trip.

These vehicles have to satisfy tight requirements about tyre tread, air conditioning performance, and general neatness. If a vehicle comes in bad condition, you must quickly call the agency hotline before you agree to the dispatch.
