The A4 is a major road linking Bristol and London. It covers a total distance of 101.2 miles and is widely used by commuters travelling between these two cities. It dates back to the 1930s when it was constructed, replacing what had been a network of secondary roads connecting the two cities. It was upgraded in 1967, bringing it up to motorway standards, and it is now a popular route for motorists and lorry drivers.

The busiest times for the A4 are typically during weekday morning and evening rush hours when it can become very congested due to commuters travelling between Bristol and London. The A4 tends to be much quieter during weekends and evenings when it is used by leisure drivers, making it a relatively safe road during off-peak hours.

According to the most recent statistics, the A4 has an accident rate of 17 per 100 million vehicle miles, which is lower than the national average of 24 and is considered relatively safe.
