After a failed attempt to run a beauty business out of the police residence where she put an ad in the local paper with the station number before Wayne could clear it with Tom Croydon, Roz purchased a car of her own, which she used for her new idea of a mobile beauty business. This was all going fine for her until she was pulled over by Nick, who gave her a ticket for doing 19 km/h over the speed limit. Roz had previously had many traffic infringements and, as a result, her license was suspended putting an end to her driving and the business. Roz was furious at Nick for this, with Roz giving both Wayne and Nick a hard time over it. Wayne tried to reason with Nick with no success. Nick later explained to Roz his reason's for not going easy on her, telling her that his wife and daughter had been killed by a drunk driver who was speeding which prompted him to join the traffic division.
