A tunnel is the most extreme kind of shadow trap: from glaring light into darkness and back again. Add loose grit at the entrance, a damp surface and sometimes a crosswind at the exit.
Safely through the tunnel
- Slow down beforehand: Ease off before the entrance so your eyes have time to adjust.
- Prepare your visor: Open a tinted visor or flip up your sun visor before the tunnel.
- Think about the exit: Expect glare and crosswinds as you ride out.
