KwaZulu-Natal Transport MEC Willies Mchunu is to investigate the use of blue lights by all mayors, MEC's and councillors in the province, SABC radio news reported on Saturday.
He tabled guidelines and regulations on the usage of blue lights in the provincial legislature in Pietermaritzburg on Friday.
This comes after journalist Tim Ncube and a VIP protection officer were killed in a head-on collision in Kwamsane.
The two were travelling in opposite directions on the N2 on Monday night when the accident happened.
The officer was driving a blue-light vehicle that formed part of King Goodwill Zwelithini's cavalcade.
Two other passengers in his car were seriously injured.
Ncube had one passenger in his car who was also seriously injured.
In November 2008, two members of a blue-light VIP Protection Unit, Constable Hlanganani Nxumalo and Caiphus Ndlela, appeared in court after Nxumalo allegedly fired shots at a car on the N3 near Ashburton. Six people were injured. - Sapa
