At traffic lights, the sequence of lights and their meanings are as follows:
- Red indicates to stop and wait behind the stop line.
- Red and amber signify to stop and wait.
- Green signals to proceed if the way ahead is clear.
- Amber instructs to stop unless you’ve already crossed the stop line or are too close to it, and stopping might cause an incident.
- Red is as described above (stop).
In some instances, there may be a green filter arrow, indicating that you can proceed in the direction of the arrow, even if the main light is not green.
If the traffic lights are malfunctioning, proceed with extreme caution, as no one has priority. A sign may indicate this issue.
Red flashing lights are typically found at level crossings, lifting bridges, or outside fire stations. You must come to a stop when these lights are flashing.
On motorways, signals on overhead gantries or at the roadside may be accompanied by flashing lights:
- Amber flashing lights warn of a hazard (e.g., fog, lane closures, instructions to exit at the next exit) or indicate a temporary maximum speed limit.
- If red lights flash on a signal and a red X is displayed, it is imperative not to drive in the lane indicated as closed beyond the signal.
- If red lights flash on a signal in the central reservation or on the side of the road, along with a lane closed sign, it is prohibited to proceed beyond the signal in any lane. If red lights flash at the beginning of a slip road, you must not enter the slip road or attempt to merge onto the motorway at that junction.
