Agressive hooting

[Tom Richardson]

Be careful with that postboxer. If you pull onto a roundabout in front of a vehicle already on the roundabout and it runs in to you the courts are likely to hold you liable and your insurers not defend against a claim by the other party. There's a chance of mitigation if they were indicating left to suggest they intended to turn off at the junction you were entering the roundabout from but even then you're very unlikely to escape all the blame.

Worse still, there are people around who are well aware of that and prepared to run into you on purpose so they can claim from you.
