The phrase 'all liability for negligence' in the Motor Vehicle (Third Party Insurance) Act 1943 (WA) policy encompasses liability for negligence howsoever arising — in tort, breach of contract, or breach of statutory duty — and is not limited to the tort of negligence. A person driving a motor vehicle on private property where no driver's licence is required under the Road Traffic Act 1974 (WA) is not 'unlicensed to drive' within the meaning of the policy warranty.
