Stage Three Road Safety Audit Checklist

Completion of Construction

The Road Safety Audit Team should consider whether the design has been properly translated into the scheme as constructed and that no inherent road safety defect has been incorporated into the works.

Particular attention should be paid to design changes, which have occurred during construction.

List C1 – General


Possible Issues

Departures from

Are there any adverse road safety implications of any Departures from Standard granted since the Stage 2 Road Safety Audit?


Does drainage of roads, cycle routes and footpaths appear adequate?

Do drainage features such as gullies obstruct footpaths, cycle routes or equestrian routes?

Climatic Conditions

Are any extraordinary measures required?


Could planting obscure signs or sight lines (including during periods of windy weather)?

Do  earth bunds obscure signs or visibility?

Could trees (new or when mature) be a potential hazard to an errant vehicle?

Could planting affect lighting or shed leaves onto the carriageway?

Public Utilities

Can maintenance vehicles stop clear of traffic lanes? If so, could they obscure signs and sight lines?

Are boxes, pillars, posts and cabinets located in safe positions away from locations that may have a high potential for errant vehicle strikes? Do they interfere with visibility?

Are any special accesses/parking areas provided safe?
Are there any utility inspection chambers in live traffic lanes and/or wheel tracks?

Are any utility service covers and gullies located in the verge level with the surrounding ground so as not to present a potential hazard to an errant vehicle?


Is the visibility to/from accesses adequate?

Are the accesses of adequate length to ensure all vehicles clear the main carriageway?

Skid Resistance

Do any joints in the surfacing appear to have excessive bleeding or low skid resistance?

Do surface changes occur at locations where they could adversely affect motorcycle stability?

Fences and Road
Restraint Systems

Is the restraint system adequate?

In the case of wooden post and rail boundary fences, are the rails placed on the non-traffic side of the posts?

Adjacent Development

Have environmental barriers been provided and do they create a hazard?

Bridge Parapets

Is the projection of any attachment excessive?

Network Management

Have appropriate signs and/or markings been installed in respect of Traffic Regulation Orders?


List C2 – Local Alignment


Possible Issues


Are the sight lines clear of obstruction?

New/Existing Road

Is there a need for additional signs and/or road markings?


List C3 – Junctions


Possible Issues


Are all visibility splays clear of obstructions?

Road Markings

Do the carriageway markings clearly define routes and priorities?

Have all superseded road markings and studs been removed adequately?


Can the junction be seen from appropriate distances and is the signing adequate?

Where chevron signs are required, have they been correctly sited?

Traffic Signals

Can the signals be seen from appropriate distances?

Can drivers see traffic signal heads for opposing traffic?

For the operation of signals:

Do signal phases correspond to the design?

Do NMU (Non Motorised User) phases give adequate crossing time?

Can NMUs mistakenly view the “green man” signal for other NMU phases?

T, X and Y

Are priorities clearly defined?

Is signing adequate?


List C4 – Non Motorised User (NMU) Provision


Possible Issues


Has suitable fencing been provided?


Are the following adequate for each type of crossing (bridges, subways, at grade)?
(a) visibility
(b) signs
(c) surfacing
(d) other guardrails
(e) drop kerbing or flush surfaces
(f) tactile paving


Do the following provide sufficient levels of road safety for cyclists on, or crossing the road?
(a) visibility
(b) signs
(c) guardrails
(d) drop kerbing or flush surfaces
(e) surfacing
(f) tactile paving


Do the following provide sufficient levels of road safety for equestrians?
(a) visibility
(b) signs
(c) guardrails


List C5 – Road Signs, Carriageway Markings and Lighting


Possible Issues


Are the visibility, locations and legibility of all signs (during daylight and darkness) adequate?

Are signposts protected from vehicle impact or passively safe?

Will signposts impede the safe and convenient passage of pedestrians and cyclists?

Have additional warning signs been provided where necessary?

Message Signs

Can VMS be read and easily understood at distances appropriate for vehicle speeds?

Are they adequately protected from vehicle impact or passively safe?


Does the street lighting provide adequate illumination of roadside features, road markings and non-vehicular users to drivers?

Is the level of illumination adequate for the road safety of NMU's

Is lighting obscured by vegetation or other street furniture?


Are all road markings/studs clear and appropriate for their location?

Have all superseded road markings and studs been removed adequately?
