The Swedish Transport Agency Transportstyrelsen has given Volvo self-driving cars venture Zenuity approval to begin testing driverless cars on public roads. The cars will be tested at a maximum speed of 80km/hour (50mph) on three Swedish highways. Throughout all tests a trained driver will sit behind the wheel, although will keep their hands off it unless an intervention is required. Zenuity is a joint venture between car giant Volvo and Veoneer, a spin-off of vehicle safety company Autoliv specialising in autonomous driving software. The three roads that the self-driving cars will be tested on are the E4 between Stockholm and Malmö, the E6 between Gothenburg and Malmö and road 40 between Jönköping and Gothenburg.
