What the DGT says if your car starts to float

The DGT advises maintaining calm if the vehicle begins to float and is swept away. This note covers only that recommendation, not a full sequence of actions for a flood.

Key points

The DGT advises drivers to remain calm if their vehicle begins to float and is swept away. This article focuses solely on that specific recommendation and does not provide a complete action guide for flood emergencies.

The specific DGT recommendation

The DGT indicates that if the vehicle begins to float and is swept away, drivers should attempt to remain calm. This article collects only that recommendation: it is not a complete sequence of actions for a flood. It can be consulted in the official DGT guide on what to do in a flood.

Do not attempt to cross a flooded road

The depth of a flooded road or watercourse cannot be judged by eye. Therefore, RTVE reports the warning not to attempt to cross them by car or on foot. This recommendation is distinct from the DGT's indication for the case where the vehicle has already started to float or is being swept away.

How to distinguish the two indications

The two sources refer to different situations: RTVE warns about attempting to cross a flooded road, while the DGT records what to do if the vehicle has already started to float and is being swept away. The recommendation to remain calm is limited to that scenario; it does not by itself complete an action guide.
