Stage One Road Safety Audit Checklist

Completion of Preliminary Design

List A1 – General


Possible Issues

Departures from

What are the road safety implications of any approved Departures from Standards or Relaxations?

Are these strategic decisions within the scope of the Road Safety Audit?


How safely do the cross-sections accommodate drainage, ducting, signing, fencing, lighting and pedestrian and cycle routes?

Could the scheme result in the provision of adverse camber?


What are the road safety implications if the standard of the proposed scheme differs from adjacent lengths of highways?


Will the new road drain adequately, or could areas of excess surface water result?

Could excess surface water turn to ice during freezing conditions?

Could excessive water drain across the highway from adjacent land?


Could areas of landscaping conflict with sight lines (including during windy conditions)?


Could utility apparatus be struck by an errant vehicle?

Could utility apparatus obscure sight lines?


Has adequate provision been made for vehicles to stop off the carriageway including picnic areas? How will parked vehicles affect sight lines?

Could lay-bys be confused with junctions?

Is the lay-by located in a safe location? (e.g. away from vertical crests or tight horizontal alignments with limited visibility)


Can all accesses be used safely?

Can multiple accesses be linked into one service road?
Are there any conflicts between turning and parked vehicles?

Emergency Vehicles

Has provision been made for safe access and egress by emergency vehicles?

Future Widening

Where a single carriageway scheme is to form part of future dual carriageway, is it clear to road users that the road is for two-way traffic?

Adjacent Development

Does adjacent development cause interference/confusion? (i.e. lighting or traffic signals on adjacent road may affect a road user’s perception of the road ahead)

Basic Design

Are the overall design principles appropriate for the predicted level of use for all road users?


List A2 – Local Alignment


Possible Issues


Are horizontal and vertical alignments consistent with required visibility?

Will sight lines be obstructed by permanent and temporary features e.g. bridge abutments and parked vehicles?

New/Existing Road

Will the proposed scheme be consistent with the standard of provision on adjacent lengths of road and if not, is this made obvious to the road user?

Does interface occur near any potential hazard, i.e. crest, bend, after steep gradient?

Vertical Alignment

Are climbing lanes to be provided?

Will the vertical alignment cause any “hidden dips”?


List A3 – Junctions


Possible Issues


Is provision for right turning vehicles required?

Are acceleration/deceleration lanes required?

Are splitter islands required on minor arms to assist pedestrians or formalise road users movements to/from the junction?

Are there any unusual features that affect road safety?

Are widths and swept paths adequate for all road users? Will large vehicles overrun pedestrian or cycle facilities?

Are there any conflicts between turning and parked vehicles?

Are any junctions sited on a crest?

Is the junction type appropriate for the traffic flows and likely vehicle speeds?


Are sight lines adequate on and through junction approaches and from the minor arm?

Are visibility splays adequate and clear of obstructions such as street furniture and landscaping?

Will the use of declaration or acceleration lanes obscure junction visibility?


List A4 – Non Motorised User Provision


Possible Issues

Adjacent Land

Will the scheme have an adverse effect on safe use of adjacent land?


Have pedestrian and cycle routes been provided where required?

Do shared facilities take account of the needs of all user groups?

Can verge strip dividing footways/cycleways and carriageways be provided?

Where footpaths have been diverted, will the new alignment permit the same users free access?

Are footbridges/subways sited to attract maximum use?

Is specific provision required for special and vulnerable groups? (i.e. the young, older users, mobility and visually impaired)

Are tactile paving, flush kerbs and guard railing proposed? Is it specified correctly and in the best location?

Have all NMU needs been considered, especially at junctions?

Are these routes clear of obstructions such as signposts, lamp columns etc?


Have needs been considered?

Does the scheme involve the diversions of bridleways?


List A5 – Road Signs, Carriageway Markings and Lighting


Possible Issues


Is there likely to be sufficient highway land to provide the traffic signs required?

Are sign gantries needed?

Have traffic signs been located away from locations where there is a high strike risk?


Is scheme to be lit?

Has lighting been considered at new junctions and where adjoining existing roads?

Are lighting columns located in the best positions? (e.g. behind safety fences)


Will poles/columns be appropriately located and protected?

Road Markings

Are any road markings proposed at this stage appropriate?


Require Assistance with a Road Safety Audit?

Sanderson Associates have extensive experience in providing Road Safety Audits for a wide variety of major and minor developments throughout the whole of the UK, Isle of Man and Ireland.

One of our Road Safety Auditors holds the Road Safety Audit, Highways England Approved Certificate of Competency, we are therefore able to carry out Road Safety Audits on the Trunk Road Network that comply with the detailed requirements of GG119 (formerly HD19/15) of the Design Manual for Roads and Bridges Volume 5 Section 2.

We would be pleased to provide you with our competitive fee proposal to provide you with our Road Safety Audit Services, please call us on 01924 844080 or click here to complete our secure online form.
