If you know a crash is imminent, here are some steps to take that may reduce injury4:
Apply brakes - Try to slow down and minimize the impact.
Determine crash point - If possible, avoid hitting anything head-on and try to manoeuver your cycle for a side impact.
Stay on the bike - It’s best to stay on your bike if you can. Bailing or laying down your bike is best to avoid if possible.
Slide well - If a slide is unavoidable, try to relax and focus on keeping your head off the pavement.
Prepare to roll - If you are unable to avoid impact, ball up to protect yourself as much as possible.
Deciding whether to slide or ball up if you see a crash coming depends mainly on the situation. Here are some things to consider:
Slide - Sliding is considered a much better alternative to balling up and may help reduce the severity of the injury. If you’re wearing proper gear and slide well, you may get through a crash with less severe injuries.
Ball Up - Balling up is only recommended if there are no other options. If you see a crashing coming while still on your bike, pull your knees to your chest, cross your arms over your knees, and tuck your head down.
In both cases, try to stay calm, assess the damage, and then get the help you need.
