A consultation is under way into whether double yellow lines should be introduced on Stevenage's Broadwater Crescent, near the junction with Ashdown Road.
The 'waiting restriction - at any time' proposal comes after a bus company complained to Hertfordshire County Council about parked cars.
A spokesman for the council's Highways Improvement Group said: "The waiting restriction is being proposed to assist in the free movement of buses travelling through Broadwater Crescent, following representations from the bus company.
"Currently the buses are having difficulty navigating through this section due to on-street parking on the junction. The proposal will provide an opportunity for buses to navigate the route in a safer manner."
To view the proposal and provide feedback, visit hertfordshire.gov.uk/about-the-council/consultations by July 28.
