How to avoid the peak
- Leave before the peak starts or after it eases. Commonly shared advice is that even 15 to 20 minutes earlier can help.
- Compare every 30 minutes for your own route, because the quickest time is often not the one you would guess.
- Check the forecast. Rain slows traffic, and Trafixcast tells you first if rain is forecast for a slot.
