The near future could see road users carefully monitoring their speed limits and shelling out greater parking fees - if the Scottish Government implements its measures to combat climate change.
Other plans in the pipeline might include a road toll requiring a person to pay per trip, and a workplace levy where an employee will have to give a fixed annual amount for parking.
These measures of detailed 'proposals and policies' have been listed by the Government to help it succeed in cutting 42% of emissions by 2020.
Though a Government spokeswoman said the document does not necessarily reflect official policy, plans such as making motorists pay 5p per kilometre for every trip they make as an emissions charge could in fact be met with public disagreement.
A workplace parking toll, requiring an employee to pay £300 per year, as well as a 50% increase in on-street parking charges, are also being considered.
Speed rules may also be introduced so that cars run on an average speed. There are also plans to cut speed limits on some roads from 70 mph to 60 mph.
A Scottish Government spokeswoman said: "We are engaging constructively with a broad range of environmental groups, companies, trade unions and business organisations as well as all parties in Parliament.
"The discussion papers ensure a full and open discussion and have been made available as part of that engagement to illustrate a range of options that could potentially cut carbon.
"The papers do not reflect Government policy."
