Accident investigators were sent to the site to determine the exact cause of the crash. Poor tyres have long been blamed for road accidents in the UAE, particularly in the summer months when the hot road takes its toll and tyre maintenance is essential. Many commercial lorry accidents are caused by unsafe tyres and wheels, according to RoadSafetyUAE. Drivers should not exceed the maximum speed recommended by tyre makers, and correct air pressure should be maintained to avoid overheated tyres or dangerous blowouts. Worn tyres with damaged treads or cracks and bald spots might not have adequate traction on the road, making braking and steering dangerous, the organisation advises. All motorists have been encouraged to replace tyres every two years, or sooner if there have been several punctures or repairs. Tyre air pressure must also be kept at the correct level according to the vehicle load, <a href="http://www.thenational.ae/uae/transport/check-tyres-to-avoid-blowouts-during-summer-months-experts-warn">experts </a>say. <a href="http://www.thenational.ae/uae/abu-dhabi-police-and-experts-stress-tyre-safety-as-temperatures-rise">Abu Dhabi Police sa</a>y that last year 14 people were killed and seven seriously injured in 28 accidents blamed on faulty tyres.
