Question 1

What information does Colorado's blue Emergency Notification System (ENS) sign provide at a railroad crossing?

Accepted Answer

A 24/7 phone number and a DOT crossing (X-ING) number so the railroad dispatcher can quickly stop trains headed toward that crossing — Every public highway-rail grade crossing has a blue ENS sign below the crossbuck giving a 24/7 phone number and a DOT crossing number, so the railroad dispatcher can identify the exact crossing and stop trains headed toward it if there's a problem.

Question 2

What warning does the Colorado Driver Handbook give about Denver's RTD Light Rail Vehicles (LRVs)?

Accepted Answer

They weigh up to 40 tons and can't stop quickly, so drivers should never turn in front of one or drive around a lowered gate — RTD's Light Rail Vehicles weigh up to 40 tons and cannot stop quickly, so the handbook specifically warns drivers to never turn in front of an approaching LRV, never turn across the tracks without checking all directions, and never drive around a lowered gate even after one LRV has passed.

Question 3

Under Colorado's Move Over Law, what must a driver do who encounters a stopped vehicle with hazard lights flashing but can't safely change lanes?

Accepted Answer

Slow to at least 20 mph below the posted speed limit instead of changing lanes — Colorado's Move Over Law requires moving over one lane for a stopped vehicle with hazards flashing when it's safe to do so; if it isn't safe to change lanes, or the road has only one lane in each direction, the driver must instead slow to at least 20 mph below the posted speed limit.

Question 4

How slow must a Colorado driver go when passing a stopped emergency vehicle they can't move over for, on a road posted above 45 mph?

Accepted Answer

20 mph under the posted speed limit -- the required reduction on roads posted above 45 mph — When a driver can't change lanes to leave room for a stopped emergency vehicle, Colorado requires slowing to 25 mph if the posted limit is 45 mph or less, or to 20 mph under the posted limit if it's above 45 mph.

Question 5

How far before reaching a stopped school bus with flashing red lights must a Colorado driver stop, and when is stopping not required?

Accepted Answer

At least 20 feet before the bus; stopping isn't required only if a median or other physical barrier separates the driver from the bus — A driver must stop at least 20 feet before a school bus stopped with red lights flashing and remain stopped until the lights stop flashing, regardless of side of road or direction of approach -- except where a median or other physical barrier separates the driver from the bus.
