"The best advice for preparing for an accident is wear a helmet. If a car hits you...."
This is written by someone who has never been hit by a car on a bike, if that's the best advice they can offer. I would suggest, try and prevent the accident to begin with maybe a better idea. Good lights, reflective clothes, high viz and good route selection would come before a helmet in my opinion.
A cycling helmet is often mistaken for a motorcycle helmet. But it will not take the same impact. I have had accidents on both bikes and motorbikes and I think a cycle helmet has little effect if you are in a collision with a car when it comes to impact injury. But from experience I know a bicycle helmet can prevent gravel rash.
I would rather break bones than have severe gravel rash any day of the week. I have had both.
Why are we discussing helmets? I thought we were grown ups. 😁
Yes. I was wearing a helmet when I was hit head on by the drunk moped rider. 😁
