(2) For the purposes of this regulation, duty on a public holiday or on a day which would otherwise have been a rostered rest day shall be regarded as a recall to duty between 2 tours of duty only if the member, after completion of a period of such duty, is recalled for further duty.
(3) In computing any period of overtime for the purposes of regulation 22 or any period of duty for the purposes of regulation 23 (save for the purposes of paragraph (8)(f) thereof) the time occupied by such a member in relevant travelling, not exceeding such reasonable limit as may be fixed by the chief constable, shall be treated as a period of duty.
(4) For the purposes of regulation 42 the use of a motor vehicle for relevant travelling shall be treated as such use for the purpose of duties performed by the member concerned.
(5) Relevant travelling expenses shall be treated as expenses incurred in the execution of duty and, unless they are expenses in respect of which an allowance is payable under these regulations, the member concerned shall be reimbursed those expenses to the extent that they do not exceed such reasonable limit as the Police Authority may fix.
