I-40 both directions out to city limits
Barstow PD can be frequently spotted hiding in on the median in the shade under the overpasses. In the California deserts overpasses are always traditional speedtrap locations both for local police and CHP. Barstow PD stopped me around midnight for burnt out license plate lights. Fortunately I was not speeding, and he let me go when it was clear I was not drunk or doing anything else illegal. Just keep in mind, burnt out lights etc. are the sort of nuisance infractions they look for when they need an excuse to go on a fishing expedition for bigger crimes. So keep your car in good shape!
