I don’t recommend specifically asking for an inspection sometimes you might get an officer in a bad mood. If you have an electronic scale pass, try removing the batteries unless you’re on a toll road; this will require you to stop at each open scale. You’ll likely get a Level 2 or 3 inspection soon. Also, inspection blitzes are common in May, and states like Washington, Virginia, North Carolina, and California often perform Level 3 inspections.
