Do You Have to Stop Twice at a Stop Sign?
No, most often stopping behind another car at a stop sign does not count as your legal stop.
According to Section 186 of the Motor Vehicle Act, you must bring your vehicle to a complete stop at a specific location—the stop line, crosswalk, or intersection edge—regardless of whether you already stopped behind another vehicle.

If you stop at a stop sign, does the cross-traffic always have the right-of-way? Most drivers in British Columbia assume the answer is yes, but the legal reality under the B.C. Motor Vehicle Act (MVA) might surprise you.

Why would a website that specializes in road safety and traffic law in British Columbia refer to the German Road Traffic Regulations? The German regulations start with what amounts to a social contract in contrast to our Motor Vehicle Act which only contains rules that people must obey. It sets a core philosophy, framing road use as a shared responsibility for everyone and then creates a framework to guide it.
