Rules

Our Rules Are Simple:

We ask all visitors to respect the site, the staff, and fellow users. That simply means responsible driving, decent vehicles and a good attitude. Follow these, and you're guaranteed a great time at Bio4x4.

Please note, we do not allow 'Bangers' or 'Scrappers' - our club rules clearly state the minimum standards we require - you could be turned away if your car does not meet expectations. Experienced drivers will know what is acceptable, if you are new to us, a good rule of thumb is that a road worthy vehicle with a recovery point is likely to be fine. A dedicated off road vehicle should have good recovery points, steering, brakes and tyres. Our full club rules can be found in our membership app see the "Join Us" section for more details. 

If you are unsure, feel free to reach out to us on our Facebook page and seek advice.
