Several years ago a speeding truck involved in a fatal accident in NSW was found to have its compulsory speed limiting device (which would restrict its speed to 100kph) disconnected. Other trucks in the fleet were then inspected and found also to have their speed limiting devices disconnected. The owner of the truck fleet (who permitted drivers to disconnect the speed limiting devices to speed up deliveries) could be liable under which legal principle? a. contributory negligence b. vicarious liability c. volenti d. unlimited liability
