Authority
The Department is legally authorized to temporarily reduce speed limits based on Colorado Revised Statute §
42-4-1102(1). The reduction must be based on an assessment of how the construction or maintenance work
activity will impact traffic flow through the work zone. The traffic assessment, traffic investigation, or maintenance
work order must be documented in this form. Additionally, CDOT projects which include recommendations
for reduced speeds as part of the TSM&O evaluation shall include a copy of the evaluation report with
this form. Procedural Directive 1502.2 "Temporary Reduction in Speed Limits" must be reviewed prior to
execution.
Speed reductions shall only apply while the conditions exist that warrant the reduction. This is not always for
the entire length and duration of the project. The permanently posted speed limits shall be effective upon
completion of the speed reduction and signs shall be either unmasked or re-installed.
Note: If no work is occurring, temporary traffic control speed limit signs must be removed or masked within one
hour of the completion of work.
The Chief Engineer shall delegate signature authority to the Region Traffic Engineers or designee, the LTC Ops I
or higher (Maintenance Superintendents, Deputy Superintendents) to determine appropriate temporary
speed limits. This Form 568 shall be routed to the Region Traffic Engineer for speed limit reductions associated
with the issuance of a permit, an engineering project or a local agency project on a state highway, or a reduction
of speed limit outside of Table I.
