This FAQ strengthens your understanding and supports accurate decision making for the Spanish driving theory exam in Spain.

What does the R-304 'No U-turn' sign mean?

The R-304 sign specifically prohibits drivers from making a U-turn. This means you cannot turn around to go in the opposite direction at this point on the road. You must continue on your current path or look for an alternative, permitted route.

When does the R-304 restriction end?

The restriction imposed by the R-304 'No U-turn' sign remains in effect until you encounter a sign that cancels the prohibition, or until you reach a junction or intersection where other traffic rules apply. Always be aware of your surroundings and look for the end of the restriction.

Are there any exceptions to the 'No U-turn' rule?

Generally, the R-304 sign indicates a strict prohibition. However, always check for any additional panels accompanying the sign, as these might specify exceptions based on vehicle type, time of day, or specific road conditions. Without such panels, assume a U-turn is strictly forbidden.

What are common mistakes related to the R-304 sign in the theory exam?

A common mistake is assuming you can make a U-turn after a junction if the 'No U-turn' sign is still visible. The restriction typically continues past the junction unless a specific 'end of restriction' sign is present. Another error is confusing it with 'No entry' or 'No stopping' signs. Always remember R-304 is exclusively about U-turns.

What should I do if I see the R-304 sign and need to go back?

If you see the R-304 'No U-turn' sign and need to reverse your direction, you must find a permitted alternative. This usually means continuing to the next junction or a designated turning point where U-turns are allowed, or exiting the road and finding a safe place to re-enter in the desired direction.
