The consumer advocacy group sent a letter to Finance Minister Nicolas Marceau reminding him drivers frequently have to shoulder price hikes.
The organization said it is worried about the PQ's coming announcements because there were no pre-budget consultations with the CAA-Québec. The organization said it fears drivers could be an easy target.
According to CAA-Québec, drivers burdened by high gas prices, expensive license fees, and millions of dollars collected in taxes to fund roadwork and public transit have asked for help.
Transport Minister Sylvain Gaudreault said recently he would not push for another tax hike on gas prices but said it remains a possibility.
