The SIG17 Steady Red Light signifies a complete closure of the road. It means you cannot proceed any further and must stop before the signal. This is not a temporary stop signal; the road is genuinely blocked.
You must stop your vehicle before the SIG17 signal. Look for detour signs to guide you to an alternative route. Do not attempt to drive past the signal or bypass the closure, for example, by using the shoulder of the road.
Generally, no. The steady red light indicates a full closure. The only exception might be if traffic control staff explicitly instruct you to proceed or to wait. Always follow official instructions or detour signs.
A common trap is confusing this steady red light with traffic signals at junctions that temporarily stop traffic before allowing it to proceed. The SIG17 specifically means 'road closed' and requires you to stop and find another way, not to wait for a green light.
If you encounter a SIG17 steady red light without clear detour signs, you should assume the closure is significant. Look for other guidance, such as temporary traffic management personnel, or choose an alternative route yourself. Never assume the closure is minor or will be lifted quickly.
