Q: Erect _____________ sign 250' in advance of any section of roadway where
traffic must travel on a planed surface. ANSWER: Grooved Pavement (CMS
2019, section 614.055) ✔✔
Note: This sign is critical for motorcyclists and bicyclists, as "milled" or planed
surfaces can significantly affect the stability of two-wheeled vehicles.
Q: Furnish cones, drums, signs, sign support, barricades, and other traffic
control devices that are certified to meet _____________. ANSWER: NCHRP
350 (CMS 2019, Section 614.03) ✔✔
Evolution of Standards: While NCHRP 350 was the long-standing standard for
"crashworthy" devices, it has largely been replaced by MASH (Manual for
Assessing Safety Hardware). However, many specifications (like CMS 2019) still
reference NCHRP 350 for existing inventory. These certifications ensure that if a
vehicle hits a sign stand or drum, the device will break away or deform safely
rather than becoming a deadly projectile.
Q: (T/F) Escort transport vehicles without proper strobe lights, LED warning
lights or rotating beacons or conspicuity tape to and from the work zone only
with the approval of the Engineer. ANSWER: True (CMS 2019, section
614.11) ✔✔
Safety Protocol: High-visibility lighting and conspicuity tape (reflective striping)
are non-negotiable for equipment operating near traffic. If a vehicle lacks these, it
poses a "ghost" hazard, requiring a formal escort and engineering approval to move
within the project limits.
, Q: Repair or replace unsatisfactory markings immediately and at no
additional cost to the department, if the marking were in place for __________
days or less. ANSWER: 120 calendar days (CMS 2019, section 614.11) ✔✔
Contractual Obligation: This acts as a "warranty" period. If temporary or
permanent pavement markings fail (fade, peel, or lose reflectivity) within the first
120 days, the contractor is liable for the cost of the fix.
Quick Reference: CMS Compliance Checklist
Signage: Must be visible and placed at correct lead-in distances (e.g., 250').
Crashworthiness: Must meet NCHRP 350 or MASH standards.
Markings: Must remain effective for at least 120 days.
Equipment: Must have approved lighting or a designated escort.
All barriers segments are to be marked on the top, as shown, PCB-Rxx-350-TL3.
What does the xx stand for? -ANSWER✔✔it will indicate the year casted
The contractor shall select one of the three acceptable options for terminating
portable barriers. -ANSWER✔✔Refer to NOTE ITEMS #3 a), b), and c)
Cones used for night time traffic control shall have a minimum height of
____________? -ANSWER✔✔42" (Drums/Cones, section 13B)
For construction of temporary walkways, the maximum grade shall be
_____________ unless specified otherwise? -ANSWER✔✔5% (MT110.10 (5B))
____________________ shall be used to protect pedestrians from thrown object
from passing vehicle? -ANSWER✔✔Plywood Walls ( MT-110.10 (7E))
