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.
