Interstate 40 westbound approaches the agricultural inspection station outside Needles, California. Photo taken 07/22/14.

Agricultural inspection stations lie along all Interstate highways entering California from Arizona, Nevada and Oregon. When in operation, these stations require motorists to stop as officers do a visual observation of vehicles or verbal questioning of drivers for any inbound based agricultural products.
