Get clear, practical answers to the most common questions about the P-31 - Traffic queues road sign. Learn how the sign works, what rules it represents, and how it affects real driving situations.

The P-31 sign warns drivers that traffic queues are likely to be present on the road ahead. It's a general danger warning, prompting you to reduce your speed and increase your observation well in advance of reaching the congestion.
Upon seeing the P-31 sign, you should immediately start to slow down gradually. Look further ahead to assess the traffic situation, and be prepared to adjust your speed and potentially your lane position. The goal is to merge smoothly into the queue or stop safely without abrupt braking.
The main prohibited action is ignoring the warning. You must not maintain your speed if the road ahead clearly requires more caution due to queues. It is also prohibited to wait until the hazard is directly in front of you before adjusting your speed or position; early preparation is key.
A common mistake is not slowing down early enough, or only reacting when the queue is already visible. Learners might also forget to scan ahead for the actual extent of the queue. Remember, the sign is a prompt for early preparation, not a signal to react at the last moment.
The P-31 sign is part of the general danger warning signs in Spain and can be placed on various types of roads, including motorways, dual carriageways, and urban or rural roads, wherever traffic queues are a potential hazard.
If a supplementary panel is present, it will usually indicate the distance to the traffic queues or the length of the expected queue. Always apply the warning in conjunction with the information on the panel. For example, a panel showing '500m' means you should start preparing for queues 500 metres ahead.
