Bosses at County Hall are being accused of putting their need for parking spaces ahead of safety.
For the past three years, people living opposite the Leicestershire County Council headquarters in Leicester Road, Glenfield, have faced a growing problem of council staff parking on the lane outside their homes.
The 50mph downhill stretch has two carriageways for traffic and the third lane which was put there when County Hall was built in the 1970s.
It allows residents to safely pull out of their homes without going straight into the traffic.
County Hall wants to deal with the parking problem using a two-hour limit but, tomorrow, residents at the Blaby Highways Forum will present a petition rejecting the plan, fearing it will create a busy short-term car park on their street.
Annette and Peter Oliver, who live in Leicester Road, collected the signatures of 40 residents saying "no" to the two-hour waiting limit. Peter said: "That lane was put there for the safety of residents as it's dangerous to turn on and off the dual carriageway.
"Over the past three years, more staff from County Hall have been parking along here and every day it's solid.
"Sometimes the traffic is moving too fast and when you're approaching the house you just have to abort and go around the block again."
Annette said: "It's extremely scary pulling out of the drive and all the residents have had horrendous experiences."
Chris Merkin, 52, who also signed the petition, said: "It's really a County Hall overflow car park and it's just going to be a short-stay, rather than a long-stay, car park if they put in the two-hour restriction."
Marie Watts, 36, has two children aged four and five and is worried about their safety when she reverses out of her driveway.
She said: "The cars park on both sides of my drive, so it really affects visibility and my main concern is for my kids in the back seat. It's getting worse and we can't even slow down enough to turn into the house without getting beeped at by everyone behind."
A spokesman for Leicestershire County Council said: "We are committed to finding an acceptable solution to the parking issues in the area and have proposed a scheme of parking restrictions.
"These proposed orders still allow for parking over a limited period of time. However, should there prove to be a need for further restrictions, these can be introduced.
"This scheme will be implemented at the same time that a 186-space extension of the County Hall car park is due to be opened in early July and will also coincide with a push to encourage staff to use our own car park facilities."
