When my children get on/off the motorbike, I want them to start doing it by standing on the side that doesn't have the tailpipe or exhaust because the tailpipe might be very hot especially when the motorbike has been running for a long time. The children might get burned if they happen to touch the tailpipe with their legs.
Is it correct to say "You must get on/off the motorbike from the left side"?
