Roadside drug testing (RDT) roadside checkpoints are designed to catch people driving with illegal drugs in their bodies – regardless of whether or not those drugs affect the driving.
Why then do the police not much more efficiently set up checkpoints outside shopping centres, schools, hospitals, post offices, banks, and parliament etc? That way they would not have to disrupt the flow of traffic on the roads and would soon have half the population under lock and key.
Add mandatory on-the-spot strip-searches and rectal probes and everybody would be only too happy to comply with COVID-19 restrictions and stay at home. That way we will have solved two problems at once.
