Under S6B of the Road Traffic Act 1988, which type of samples may be administered at the scene or station?

• A. Sweat or saliva samples.
• B. Blood samples.
• C. Hair samples.
• D. Urine samples.

Answer: (B)

The main idea here is that S6B gives the police the power to obtain a chemical sample to determine impairment due to drugs, and this power includes taking a blood sample either at the scene or at the police station. Blood is used because it provides a direct measure of substances in the bloodstream, which is especially important for confirming the presence and level of drugs (and certain intoxicants) when someone is suspected of driving while impaired. This ability to collect a blood sample at the scene or at the station enables timely and robust evidence gathering, which is why blood is the correct choice. Sweat, saliva, hair, and urine are not the primary specimens specified for at-scene administration under this provision, and while other tests may involve those fluids in different contexts, the question targets that S6B explicitly covers blood samples in these settings.
