Catalogue section 3.5
Other prohibition and restriction signs (R-300–R-310)
They ban or limit specific manoeuvres and behaviour: speed, overtaking, turns, stopping and parking.
How to recognise them: A circle with a red border and a white background, carrying the figure or symbol of what it forbids.
How this group is laid out
What this group bans is manoeuvres and behaviour, not access. R-300 and R-301 limit how you drive: the gap to the vehicle in front and the maximum speed. The definition of R-301 also says how far it applies: until the next end-of-speed-limit, end-of-restrictions or different maximum-speed sign; if it shares a post or board with a danger sign, until the danger ends; and, on a road without priority, until you leave a junction with a priority road.
R-302 to R-304 ban turning and U-turns, and R-305 and R-306 overtaking. R-307 and R-308 concern the side of the carriageway the sign stands on: R-307 bans stopping and parking; R-308 bans only parking, and stopping is still allowed. Their letters narrow down where or when: in both directions from the sign, in the direction of the arrow, in one half of the month, or in front of a vehicle entrance. The group ends with the restricted parking zone (R-309) and R-310, a reminder of the general ban on sounding your horn except to avoid an accident.
How to tell them apart
Signs in this group that look alike, and what separates them according to their definitions.
R-307
R-308R-307 bans stopping and parking; R-308 only parking, and its definition says so in as many words: it does not ban stopping. Both apply on the side of the carriageway where the sign stands and, unless stated otherwise, up to the next junction.
R-302
R-303
R-304R-302 bans turning right and R-304 making a U-turn. R-303 bans turning left and, according to its own definition, making a U-turn as well.
R-305
R-306R-305 bars everyone from overtaking motor vehicles where doing so means moving into the side reserved for oncoming traffic. R-306 only affects lorries with a maximum authorised weight over 3,500 kg, but bars them from overtaking even without crossing over.
R-307a
R-307b
R-307cR-307a bans stopping and parking in both directions from the sign, up to the nearest junctions or R-307b and R-307c signs. R-307b and R-307c ban it only in the direction their arrow points.
R-308c
R-308dR-308c bans parking in the first half of the month and R-308d in the second; both change over at the same hour of the morning. Neither bans stopping.
20 signs
R-300
Minimum gap
You may not drive closer to the vehicle in front than the distance shown, except when you are about to overtake. With no figure, it is a general reminder to keep the legally required safe distance between vehicles.
R-301
Maximum speed
You may not exceed the speed shown, in km/h. It applies from the sign until the next end-of-speed-limit, end-of-restrictions or other maximum-speed sign — unless it shares a post or board with a danger-warning sign, in which case it ends when the hazard does. On a road without priority it stops applying once you leave a junction with a priority road. If the limit shown is the same as the maximum speed for that type of road, it is a general reminder not to exceed it.
R-302
No right turn
Turning right is prohibited.
R-303
No left turn
Turning left is prohibited. This also bans making a U-turn.
R-304
No U-turn
Making a U-turn is prohibited.
R-305
No overtaking
On top of the general overtaking rules, no vehicle may overtake a motor vehicle on the carriageway where doing so means moving into the side reserved for oncoming traffic. It applies from the sign until the next end-of-no-overtaking or end-of-restrictions sign. Placed where overtaking is already prohibited by the rules, it is a general reminder of that ban.
R-306
No overtaking for lorries
Lorries with a maximum authorised mass (MAM) over 3,500 kg may not overtake motor vehicles on the carriageway, even when doing so would not mean crossing into the oncoming side. It applies until the next end-of-no-overtaking or end-of-restrictions sign.
R-307
No stopping or parking
You may neither stop nor park on the side of the carriageway where the sign stands. Unless stated otherwise, it runs from the sign to the next junction in your direction of travel.
R-307a
No stopping or parking, both directions from the sign
No stopping or parking on the sign's side of the carriageway, along the stretch between the nearest junctions or R-307b and R-307c signs on either side of it.
R-307b
No stopping or parking, in the direction of the arrow
No stopping or parking on the sign's side of the carriageway, from the sign to the nearest junction or R-307c sign in the direction the arrow points.
R-307c
No stopping or parking, in the direction of the arrow
No stopping or parking on the sign's side of the carriageway, from the sign to the nearest junction or R-307b sign in the direction the arrow points.
R-308
No parking
You may not park on the side of the carriageway where the sign stands. Unless stated otherwise, it runs from the sign to the next junction in your direction of travel. Stopping is still allowed.
R-308c
No parking, first half of the month
No parking on the sign's side of the carriageway from 9:00 on the 1st until 9:00 on the 16th. Unless stated otherwise, it runs from the sign to the next junction ahead. Stopping is still allowed.
R-308d
No parking, second half of the month
No parking on the sign's side of the carriageway from 9:00 on the 16th until 9:00 on the 1st. Unless stated otherwise, it runs from the sign to the next junction ahead. Stopping is still allowed.
R-308e
No parking across an entrance
Parking in front of a vehicle entrance is prohibited.
R-308f
No parking, both directions from the sign
No parking on the sign's side of the carriageway, along the stretch between the nearest junctions or R-308g and R-308h signs on either side of it. Stopping is still allowed.
R-308g
No parking, in the direction of the arrow
No parking on the sign's side of the carriageway, from the sign to the nearest junction or R-308h sign in the direction the arrow points. Stopping is still allowed.
R-308h
No parking, in the direction of the arrow
No parking on the sign's side of the carriageway, from the sign to the nearest junction or R-308g sign in the direction the arrow points. Stopping is still allowed.
R-309
Time-limited parking zone
Parking here is time-limited and you must display the time you started, in the prescribed way. The maximum stay, the hours the limit applies and whether parking is paid may be shown on the sign itself, on a board or on a supplementary panel.
R-310
Use of horn prohibited
A reminder of the general ban on sounding your horn, except to avoid an accident.
