STAR and non-STAR stations both set their own posted prices — there's no state-mandated STAR markup. Some vehicles are required by your DMV renewal notice to test at a STAR station, regardless of price. See our posted price on-site or on our services page. Prices are set per station, not by BAR — see our posted price for the exact cost.
