The curfew in Ft. Mohave, Arizona is 10 p.m. to 5 a.m. Sunday through Thursday and 11 p.m. to 5 a.m. Friday and Saturday.  This curfew applies to anyone under 18 years of age.

Since Ft. Mohave is located in unincorporated Mohave County just outside of Bullhead City Arizona, the curfew law is set by a Mohave County Ordinance (96-1). 

You should be aware that the curfew laws may be different when you enter the Bullhead City city limits or nearby Indian Reservation land.
