Driving with uncorrected defective eyesightN.I.
154.—(1) If a person drives a motor vehicle on a road while his eyesight is such (whether through a defect which cannot be or one which is not for the time being sufficiently corrected) that he cannot comply with any requirement as to eyesight prescribed under Part II for the purposes of tests of competence to drive, he shall be guilty of an offence under this Order.
(2) A constable having reason to suspect that a person driving a motor vehicle may be guilty of an offence under paragraph (1) may require him to submit to a test for the purpose of ascertaining whether, using no means of correction other than he used at the time of driving, he can comply with the requirement as to eyesight prescribed under Part II for the purposes of tests of competence to drive; and if that person refuses to submit to the test he shall be guilty of an offence under this Order.
