The OB-303 road sign, often accompanying parking or stopping prohibitions, signals that any vehicle violating the main restriction will be towed away at the owner's expense. This sign emphasizes strict enforcement, meaning immediate removal is a real possibility if you park or stop improperly. Always look for this sign in conjunction with other traffic signs to ensure you are not blocking access, especially for emergency services, or ignoring designated parking areas.
This OB-303 supplementary plate signifies that illegally parked or stopped vehicles will be towed at the owner's expense. Crucial for theory test revision, it highlights strict enforcement of parking rules in critical areas, ensuring clear passage and safety.
The towing in effect plate is a supplementary sign used with stopping and parking prohibitions or other critical restrictions. It informs drivers that the road authority may have illegally parked or dangerously placed vehicles removed, and that all costs are for the vehicle owner. This plate is often found near junctions, emergency routes, loading zones or entrances where blocking the area would create serious safety or access problems.
This plate warns that violating the rule on the main sign can lead to your vehicle being towed away at your own expense. It stresses that enforcement is strict and that wrongly stopped or parked vehicles may be removed quickly. As a driver you should only stop or park where it is clearly allowed and always leave enough space for emergency services and other traffic.
Get clear, practical answers to the most common questions about the OB-303 - Towing Regulation in Effect road sign. Learn how the sign works, what rules it represents, and how it affects real driving situations. This FAQ strengthens your understanding and supports accurate decision making for the Dutch driving theory exam in the Netherlands.
The OB-303 sign means that if you violate the parking or stopping rules indicated by a primary sign (like a no-parking sign), your vehicle will be towed away immediately and at your own expense. It serves as a strong warning against illegal parking.
You must not stop or park in a way that contravenes the main traffic sign this OB-303 sign is associated with. Essentially, any parking or stopping that is forbidden by another sign becomes subject to towing when OB-303 is present. This also includes blocking access for emergency vehicles.
To avoid your vehicle being towed, always ensure you are parking or stopping in a permitted location and manner. This means adhering strictly to any time limits, designated parking bays, and prohibitions indicated by other signs present. If unsure, find a legal parking spot nearby.
While the OB-303 sign specifically warns of towing, it's important to understand that vehicles may be towed even without this sign if they are illegally parked in a way that obstructs traffic or emergency access. However, the OB-303 sign serves as an explicit and immediate warning that towing is actively enforced in that specific location.
A common trap is underestimating the consequence of violating a parking prohibition when OB-303 is displayed. Learners might think towing is rare, but this sign indicates it's a certainty for offenders. Always treat it as a definitive 'do not park here' warning, as the theory test expects you to understand the immediate and costly repercussions.
No, the presence of the OB-303 towing regulation sign means that any violation of the associated parking restrictions will result in towing. Even if there appears to be space, if parking is prohibited by another sign (e.g., 'no stopping' or 'no parking' zones), you must not park there, or your vehicle will be towed at your expense.

The G5 sign designates an erf, a special zone within built-up areas where the street is shared closely by residents, children, cyclists, and motor vehicles. The effective speed is around walking pace, and drivers must give clear priority to pedestrians and playing children at all times. Parking is restricted to marked bays, and using the area as a fast through-route is contrary to the intended living-street character.
The taxi parking sign usually combines the parking symbol with the word taxi and marks a space where only taxis may stop and wait for customers. Other vehicles may neither park nor wait in this area, even for a short time, unless specifically allowed by an additional plate. Taxi ranks are positioned so that taxis can queue safely without hindering other traffic, while passengers can get in and out conveniently. Respecting this restriction supports efficient public transport by taxi and increases safety at busy pick up points.
