In other states, national highways are grade separated, 60 metres (200 feet) wide with a minimum of four lanes, as well as 6 or 8-lane access-controlled expressways.[12][13] The National Highways Authority of India (NHAI) has threatened the Kerala state government that it will give higher priority to other states in highway development since political commitment to better highways in Kerala has been lacking.[14] As of 2013[update], Kerala had the highest road accident rate in the country, with most fatal accidents taking place along the state's national highways.[15]
