Long journeys can be a hassle- What with contending with busy traffic on motorways or battling the dangers of driving when tired, any journey longer than your normal driving duration will put more stress on you as a driver.
Try to ease this stress by planning your journey well. If the time you will be travelling overlaps a busy time of the day such as rush hour, try to find an alternative route that does not use roads that will be particularly busy at this time. Also if your journey takes place primarily on the motorway, try to plot a good place to stop for short, regular breaks throughout the journey such as motorway services, to refresh and avoid fatigue.
Safe driving from Britannia!
