The 50 - to - 30 Illusion

After driving at high speeds , 50 mph can feel as slow as 30 mph , leading to a false sense of security .

Speed Awareness : Leaving the Motorway Safely

The Speed Perception Gap

Check Your Speedometer

Do not rely on your " feel " for speed ; physically look at your speedometer to verify your actual rate of travel when exiting .

Adjust and Recalibrate: Once you have identified your true speed , actively adjust your acceleration to match the legal limits and safety requirements of the new road .

Navigating Exit and Link Roads

Link Road Hazards

Caution is required not just when exiting the motorway entirely , but also when using link roads between different motorways .

Anticipate Sharp Bends

Unlike the long , straight stretches of the motorway , slip - roads and link roads frequently feature sharp curves that require a significant reduction in speed .

Slow Down Early

Begin your speed adjustment as you enter the slip - road or link road to ensure you can safely navigate tight turns .
