If the situation calls for a standard traffic control scheme, do the advance warning signs 

match those shown in the standard layouts in the MUTCD?

Yes No
SAFETY CHECKLIST

for Construction Projects

Do the sign messages convey the intended actions that are required to be taken? Yes No

Do the signs have the proper legends, sizes, color combinations, and reflectivity? (The 

MUTCD provides that the minimum letter size for signs should not be less than five 

inches for low volume traffic.)

Yes No

Is the location of the sign per the MUTCD? Yes No

Are the signs properly spaced? Yes No

Are the layout measurements tied to a physical feature so the Contractor can do the 

layout in the field?

Yes No

Are there existing signs within the construction zone that may conflict with the Traffic 

Control Plan?

Yes No

Do any of the existing signs obscure the view of advance warning signs? Yes No

If stage construction is used, is the signing from stage to stage consistent (sign types and 

locations)?

Yes No

If a numbered route, are the numbered routes used for the detour? Yes No

If a detour is not provided could a detour work? Yes No

Are all access points properly signed? Yes No

Is it physically possible to place the sign where indicated? Yes No

Is there sufficient horizontal clearance? Yes No

Is there a need for any pedestrian or bicycle signing? Yes No

Comments:

Channelizing Devices

Are the correct devices used for a particular operation? (Drums should be used instead 

of barricades, type II; Temporary concrete barriers should not be used as a channelizing 

device.)

Yes No

Are channelizing tapers located correctly? Yes No

Are channelizing tapers the correct length? Yes No

Are devices spaced correctly in the taper? Yes No

Are devices spaced correctly in the work area? Yes No

Do the devices meet MUTCD requirements for size, type, color, and reflectivity? Yes No

Are the devices properly ballasted (weighted down)? Yes No

Comments:

Pavement Markings

If short-term markings required, do they coincide with MUTCD 6D and Federal Lands 

Highway policy?

Yes No

Is marking consistent, especially during stage construction? Yes No

Do existing pavement markings conflict with the proposed temporary markings? Yes No

Comments:

Lighting Devices 

Are warning lights used correctly? (Warning lights, type A should be used on drums or 

barricades to mark point hazards, or on the first two devices in a taper: Warning lights, 

type B, if used, should be used on signs and the batteries should be placed no higher 

than 12 inches off the ground: Warning lights, type C should be used on drums or 

barricades used in a series for delineation.)

Yes No
SAFETY CHECKLIST

for Construction Projects

Are arrow panels placed on the shoulder adjacent to the beginning of the taper? (If 

there is limited shoulder, the arrow board should be placed in the closed lane towards 

the beginning of the taper.)

Yes No

Is there adequate sight distance for the arrow board? Yes No

Is the arrow panel being used correctly? (Arrow panels should not be used in "passing 

arrow" mode on two-lane two-way roadways, shoulder closures, or lanes shifts: For the 

cases listed above the arrow board can be used in the "caution" mode.)

Yes No

Comments: 

Barriers 

Are untreated temporary barrier ends exposed to traffic? Yes No

Is the area between the barrier and the travel lanes relatively flat (approximately 10:1)? Yes No

Are temporary barriers required due to drop-off close to the travel lanes? Yes No

Are existing barriers being removed such that the hazards they were protecting are now 

a hazard during the construction?

Yes No

Is temporary barrier properly accounted for? (For stage construction, use the greatest 

amount of barrier required for a particular stage as the barrier quantity, and remember 

to account for storing barrier during stages with less than the greatest amount for 

moving barrier.)

Yes No

Are construction areas properly shielded? Yes No

Should temporary barrier be bolted to the pavement or bridge deck do to their 

deflection?

Yes No

Are barriers flared away from the roadway in accordance with AASHTO Roadside Design 

Guide? 

Yes No

Comments:

Flaggers

If flaggers are being used are the proper warning signs displayed? Yes No

Is the flagging station visible to oncoming traffic? Yes No

When the flagger is not on station, is the flagger sign covered or removed? Yes No

Comments:

Miscellaneous

Does the Project Engineer have names and phone numbers of persons to contact in case

of emergencies?

Yes No

If there are special construction events (i.e., roadway closures) are there provisions for 

the Contractor to notify the Project Engineer in advance so the Engineer can notify 

authorities?

Yes No

Are roadway drop-offs excessive? Yes No

Does the Contract identify time restrictions placed so that the Contractor can only 

perform work during certain times?

Yes No

Is there a possibility of pedestrians and cyclists in the project area? Yes No

For projects with stage construction, when the traffic control is switched from one stage 

to the next, are there provisions in the Contract to accomplish that operation?

Yes No

Can the traffic control switching be accomplished under traffic? Yes No
