Traffic Signs & Signals: DGT theory test questions in English

Officers can require a drug test at a checkpoint. It is not limited to drivers involved in a crash, and it does not have to be done at a medical center. Drivers who break traffic rules can also be tested.

This warning sign (P-20a) tells you that you are approaching an area with frequent pedestrians, often near a crossing. Slow down and be ready to stop. Children near schools or playgrounds have their own sign (P-21). A ban on pedestrians would be a prohibition sign, not a warning sign.

A white dashed line with closely spaced dashes warns that a solid line is coming up, or that you are nearing a section with special risk. It does not mark the start of a normal dashed line or a special lane.

An officer moving an arm up and down is telling traffic approaching from that side to slow down. It is not a signal to stop, and it does not mean you can carry on without reducing speed.

This sign (R-418) marks a lane or section where paying the toll electronically is mandatory. Your vehicle must carry the device that pays the toll automatically. Cash and card payment are not accepted in that lane.

You must always obey traffic signs, even when they seem to contradict the general traffic rules. If a sign and a general rule say different things, follow the sign. Signs meant for other roads do not apply to you.

Traffic signs warn and inform road users in advance about road conditions and traffic situations. They also order or regulate how road users behave. Their purpose is not limited to confirming exceptions or supplementing the rules.

A solid line across the lane marks where you must stop when a stop sign, a crosswalk, a traffic light, an officer or a railroad crossing requires it. If none of these requires you to stop, you may cross the line without stopping. Pedestrians present are a reason to stop, not to keep going.

Traffic lights take priority over all vertical signs. With a green light, you go ahead with right of way, so you don't need to stop or yield. You obey the Stop sign only if the light is off or flashing yellow.

This sign (R-307) bans both stopping and parking. Unless another sign says otherwise, the ban starts at the sign and runs to the next intersection. It does not allow parking, and it has nothing to do with even or odd days.

This sign (S-60a) warns that a two-lane road splits ahead and the left lane branches off. It applies to all road users. It does not order a left turn, and the left branch is not reserved for faster vehicles.

This STOP sign (R-2) requires you to stop every time, at the stop line or, if there is none, just before the intersection, and then yield to traffic on the road you are entering. Visibility and the presence of other vehicles do not matter. The only exception is a traffic light, because lights rank above signs when they conflict.

This sign (P-1a) warns of an intersection where you have priority over vehicles on the cross road, whether they come from your left or your right. It applies only to the next intersection, not to the whole road, and it does not give priority to the cross traffic.

When signals conflict, the order of priority is: traffic officers, then temporary signs such as barriers, then traffic lights, then vertical signs, and last road markings. A vertical sign outranks a road marking, so you obey the stop sign. The general right-of-way rule only applies when there are no signs at all.

This panel (S-821, or S-820 when the arrow points left) tells you the distance over which the prohibition applies, in the direction of the arrow, here to the right. It does not cover both sides of the road, and it does not show the distance to the start of the prohibition.

This sign (R-413) makes it mandatory to use at least your low beams on this road. Parking lights alone are not enough. High beams are not required and could dazzle other drivers.

This sign (S-34) marks a pull-out inside a tunnel where you can move your vehicle out of the way and leave the lane clear for other traffic. If it also shows the letters SOS, the pull-out has an emergency phone. It does not mark a viewpoint or a U-turn spot.

This sign (R-406) requires all trucks and vans, whatever their weight, to use the roadway it marks. Only if the sign shows a weight figure does the rule apply just to vehicles whose maximum authorized mass (MAM) is above that figure. It is a mandatory sign, not a ban.

A red flag on a traffic officer's priority vehicle means the road is temporarily closed to traffic from that vehicle onward. Only the vehicles it is escorting may continue. It is not a stop-on-the-right order or a simple hazard warning.

This sign (S-52a) gives advance warning on a two-way road that the right lane is ending, and shows the lane change you need to make. It does not simply announce a two-way road, and it says nothing about right of way at an intersection.
