Highway Safety and Traffic Concerns in Planning Objections

Concerns about increased traffic, insufficient parking, dangerous access arrangements, or harm to pedestrian safety can all amount to valid planning objections. The important point is that these concerns need to be based on clear facts and local evidence, rather than general frustration about cars or congestion.

At Objection Experts, we regularly help residents prepare strong planning objections that identify where a proposal would create genuine and unacceptable impacts on highway safety and the surrounding road network.

Yes. Highway safety is a recognised material planning consideration. Councils are required to consider whether a development would provide safe and suitable access for all users, and whether it would have an unacceptable impact on highway safety.

That can include issues such as:

• Increased vehicle movements on unsuitable roads
• Poor visibility at site access points
• Conflict between vehicles and pedestrians
• Inadequate parking leading to overspill parking on nearby streets
• Pressure on junctions, turning areas, or narrow lanes
• Danger to cyclists, school children, or other vulnerable road users

A proposal does not have to result in constant gridlock to be unacceptable. The real issue is whether the development would create a harmful effect on safety or the proper functioning of the local highway network.

Increased traffic on unsuitable roads

One of the most common concerns is that a new development would intensify traffic on roads that are already constrained. This is especially relevant where streets are narrow, heavily parked, lack passing places, or already experience congestion at peak times.

This can be a strong point where:

• The road is effectively single-width in places
• Vehicles already struggle to pass safely
• There is no continuous footway
• The route is used by school children or pedestrians
• The development would add turning, reversing, or delivery movements in a constrained location

A planning objection should explain exactly why the local road network is unsuitable, rather than simply stating that “traffic will increase.”

Dangerous or inadequate access points

A proposed access can raise serious concerns where drivers would emerge onto a road with poor visibility, limited manoeuvring space, or conflict with passing traffic, pedestrians, or cyclists.

Examples include:

• Access onto a bend
• access close to a junction
• Poor sight-lines due to walls, hedges, parked cars, or changes in levels
• Steep gradients make entries and exits more difficult

Insufficient parking and overspill parking

Parking stress is a frequent issue in residential areas. If a development does not provide enough realistic parking, vehicles may spill onto nearby roads, causing obstruction, reduced visibility, and increased danger to pedestrians and other drivers.

This is often relevant where:

• The streets are already heavily parked
• Corners and junctions are blocked by parked vehicles
• Bin lorries or service vehicles already struggle to pass
• The proposal relies on impractical parking layouts or tandem spaces that are unlikely to work in reality

A council will often look not only at the number of spaces shown on a drawing, but also whether those spaces are genuinely usable.

Harm to pedestrian safety

Pedestrian safety is often overlooked in planning objections, but it can be one of the strongest arguments.

This may arise where a proposal would:

• Force pedestrians to walk in the carriageway
• Increase vehicle movements across a footway, especially where reversing is required
• Worsen safety for wheelchair users, parents with prams, or older people
• Rely on roads with no pavement or poor lighting

A development can be unacceptable even where the main issue is danger to people on foot, rather than danger to drivers.

A strong objection is based on specific local evidence.

General statements such as “the road is busy” or “parking is already bad” carry limited weight on their own. The most effective objections explain the real conditions on the ground and why the proposal would materially worsen them.

Useful evidence can include:

• Photographs of the road, access point, junction, or parking conditions
• Measurements of width, visibility, or available passing space
• Details of nearby schools, pedestrian routes, or bus stops
• Examples of existing congestion or blocked access
• Evidence of vehicles mounting pavements or reversing into the road
• Inconsistencies in the applicant’s transport statement or site layout

Location-specific detail is critical. A planning officer or highway officer must be able to understand exactly what the problem is and why it matters in this particular case.
