What could be a possible reason for a police officer to demand a breath test at an RTC?

A police officer may demand a breath test at a Road Traffic Collision (RTC) primarily based on reasonable cause to suspect that a driver was involved in an incident where alcohol consumption may have been a factor. This implies that if the officer observes signs or has rationale based on the circumstances of the RTC—such as vehicle damage, erratic driving behavior, or other contributing factors—they can initiate a breath test to assess the driver's level of intoxication.

The significance of this authority lies in the officer's responsibility to ensure road safety and hold accountable those who may endanger others due to impaired driving. Such a demand safeguards public safety and supports law enforcement in addressing potential alcohol-related offenses that could contribute to further accidents or injuries.

While other factors like witness reports of reckless driving or the presence of an injured party might contribute to the overall scenario, they do not provide the same direct legal basis for demanding a breath test as reasonable suspicion linked to alcohol use.
