South Australian motorists charged with causing death by dangerous driving will now face losing their licences on the spot.
New laws have passed state parliament to take people off the roads immediately if they're believed to have killed someone as a result of culpably negligent, reckless or dangerous driving.
Under the previous rules, people could continue to drive until convicted.
"These reforms will ensure swift action can be taken at the scene if and when the unthinkable happens," Attorney-General Vickie Chapman said.
"Under these laws, an individual who is charged with causing death by dangerous driving, or is reasonably believed to have committed the offence, will have their licence suspended or disqualified immediately.
"If they do not have a licence, they will be barred from applying for one."
The suspension or disqualification will remain in place until the case has been resolved and will only be lifted earlier in exceptional circumstances.
A disqualified driver can appeal to the courts to have the decision reversed but community safety will be one of the paramount considerations.
