What does an "implied consent" law require from drivers?

Implied consent laws require drivers to submit to a breathalyzer test or similar evaluations if they are suspected of driving under the influence of alcohol or drugs. This legal principle is based on the understanding that by obtaining a driver's license and operating a vehicle, a driver implicitly agrees to comply with testing requests from law enforcement agents. The rationale behind this law is to help enforce DUI laws and ensure public safety on the roads.

The other options do not reflect the core aspect of implied consent laws. Yielding to traffic signs is a standard driving rule applicable to all drivers, providing guidelines for safe operation. Providing insurance information on request pertains to legal obligations during an accident or traffic stop but is not directly related to the concept of implied consent. Notifying authorities of an accident is also a legal requirement in certain scenarios but does not fall under implied consent laws regarding sobriety testing.
