<< 5.17 If the vehicle is found to exceed the emissions limits by more than 10%, the tester should:
explain this fact;
explain that an offence has been committed;
issue a Fixed Penalty Notice in accordance with the instructions in Chapter 6;
explain that the Fixed Penalty Notice will be waived completely if the motorist can show that the vehicle had passed an MOT test within the preceding year and if the emissions defect is rectified within 14 days. (To confirm this the motorist must present to the address on the Fixed Penalty Notice two MOT test certificates (one dated before, but no more than one year before, the date the vehicle was intially stopped; the other after, but no more than 14 days after); and
for vehicles under three years old, explain that the Fixed Penalty Notice will be waived completely if the motorist can demonstrate to the satisfaction of the issuing authority that all reasonable steps had been taken prior to the test to maintain the emissions performance of the vehicle within standards and limits required by legislation and if the emissions defect is rectified within 14 days. Evidence of the former and proof of the latter (i.e. an MOT test certificate dated after, but no more than 14 days after, the date of the offence) should be sent to the address on the Fixed Penalty Notice.
