How must a load that protrudes from the front of a vehicle be signaled?

The regulation establishes that a load protruding from the front must be signaled with a white light. This signaling is only mandatory at night or in weather or environmental conditions that significantly reduce visibility. During the day with good visibility, it is not necessary to signal it.

⚠️ Critical DGT Test Traps & Distinctions

1. The Day vs. Night Signaling Rule (For Authorized Vehicles Only)

• During the Day (Good Visibility): It is not necessary to use a white light, but the load MUST still be signaled using the standard V-20 panel (the square panel with red and white diagonal reflective stripes). Leaving it without any sign is a serious violation.

• At Night (or Low Visibility): You must use both the V-20 panel AND a white light at the front (and a red light at the rear). If a journey starts during the day and extends into the night, the driver is legally required to stop and activate/install the lights as soon as visibility drops.

2. The Passenger Car Trap (Turismos)

In DGT theory questions, pay absolute attention to the vehicle type. On a passenger car (Turismo), the load is strictly prohibited from protruding from the front under any circumstances. It can only protrude from the rear. Therefore, any question implying a passenger car is carrying a load protruding from the front is a trick question, and the setup itself is illegal. Front protrusion is exclusively permitted for commercial cargo-transport vehicles.

3. Rear Protrusion Panel Trap

If a load protrudes from the rear and its width occupies the entire width of the vehicle, you must use two V-20 panels placed transversally at each end, arranged in an inverted "V" shape (/\).
