3 questions from the Nebraska practice test

1. 1. What do black on orange roadway signs identify?

   1. A permanent speed limit regulation
   2. A hospital or other motorist service
   3. A recreational or cultural destination
   4. A highway work zone
   Show answer

   A highway work zone. Black lettering on an orange background identifies a highway work zone in Nebraska. These signs can warn about the zone itself or provide directions while traffic moves through it. A service sign is associated with blue, recreation information with brown, and regulatory instructions such as speed limits with white. Treat the orange message as an early request for attention and possible action. Prepare to change lanes or reduce speed with enough space, rather than waiting until workers or barricades are immediately beside the vehicle.

2. 2. What do green and white guide signs provide?

   1. Warnings about road workers in a construction area
   2. Directional and distance information
   3. Regulatory instructions that prohibit every listed movement
   4. Reserved parking for drivers with handicapped privileges
   Show answer

   Directional and distance information. Green and white guide signs provide directional and distance information. Diagrams may show exit and entrance movements at interchanges, helping drivers select lanes and plan ahead. Orange signs identify work zones, white regulatory signs communicate laws, and handicapped parking signs reserve designated spaces. A guide sign is useful navigation information, but it does not cancel a posted regulatory instruction. Read it early, choose the needed lane in time, and continue following speed and lane controls.

3. 3. What may a flashing arrow panel tell drivers in a Nebraska work zone?

   1. A permanent speed limit is ending
   2. A recreational area begins ahead
   3. A portion of the road ahead is closed
   4. A hospital entrance is available in the next block
   Show answer

   A portion of the road ahead is closed. Nebraska describes flashing or sequencing arrow panels as devices that guide drivers into certain traffic lanes and inform them that part of the road ahead is closed. They are work-zone guidance, not recreation, hospital, or permanent speed-limit signs. Watch the direction of the arrow, merge when there is adequate space, and follow any cones, barricades, or flaggers controlling the route. The important cue is the moving or illuminated arrow paired with an altered path. It tells you to prepare for a lane change or closure before reaching the obstruction.
