NEW DRINKING AND DRIVING LAWS — BREATH TESTS – Today a police officer has to have a “reasonable suspicion” that a driver has any alcohol whatsoever in his/her body before they can demand a breath sample. Come tomorrow morning they can pull over a driver and demand a breath sample for no reason whatsoever -“no suspicion of nothing” – because they feel like it. Refusal to comply is a criminal offence.
