Revised Highway Code Rule #43: Speed Bumps
When driving your vehicle along a single carriageway that has speed bumps in place, you may drive down the middle of the road (indicated by a broken white line for your guidance) in order to avoid having to reduce your speed for the aforementioned obstacles. You have full priority; any oncoming vehicles are fully obliged to deviate their course, moving over to the kerb, or indeed come to a complete stop if necessary, in order to not prevent you from your right of way. If it appears the oncoming vehicle has not noticed you and your intended course, you should hold your main beam and/or horn in order to alert the unobservant driver to your presence.
Note: Under no circumstances give up your right of way. Do not move over to the left of the guidance line.
