Immediately after a car accident is the best time to get evidence to prove
liability for the crash. Unfortunately, it can also be the most difficult
time to collect evidence if you were seriously injured and need to focus
on your health. If you can, though, asking eyewitnesses for statements
as well as their contact information in case you need to speak to them
again is a good start. You should also ask any police, firefighters, and
EMTs that show up for copies of any official reports they create.
