Can your driver license be suspended for causing one serious collision?

Yes, in most countries, your driver's license can be suspended for causing a serious collision. The specific rules and regulations vary by jurisdiction, but in general, if you are involved in a serious collision that results in injury or property damage, you may face suspension of your driver's license. This is because driving is considered a privilege, not a right, and committing serious traffic violations can result in the suspension or revocation of that privilege.
