Work zones — Indiana Permit Test

A flashing arrow board that does not point either way signals caution but does not require you to change lanes.

A board with no direction warns of work nearby without closing your lane.

A flashing arrow board not indicating a direction either way is a signal to use caution but does not require a driver to move to another lane.

You must stop when a flagger holds a fluorescent orange or red flag straight out into your lane, and go on slowly only when the flagger directs you.

A flagger controls one lane shared by both directions, so going early can mean meeting oncoming traffic.

You must stop when a flagger extends a fluorescent orange/red flag in a horizontal position into the line of traffic.

If a flagger uses a sign paddle, stop or proceed slowly as the paddle's STOP or SLOW side tells you.

The paddle carries the same orders as a stop sign or slow sign, given by a person.

If a flagger uses a signal paddle, you must stop or proceed slowly according to the “STOP” or “SLOW” message displayed on the sign.

In a work zone, merge early when you first see the signs, unless signs tell you to zipper merge at the lane closure.

Early merging keeps traffic flowing; a late, signed zipper merge shortens the backup.

Merge early.

Automated flagger assistance devices show STOP or SLOW signs, or red and yellow lights, so flaggers can stand out of the lane.

Obey the device just as you would a flagger holding a paddle.

These devices display a “STOP” or a “SLOW” sign just like the flagger-held sign paddle or use red and yellow lights.

What does a flashing arrow board that points neither way mean?

Use caution; no lane change is needed. A board with no direction warns of work nearby without closing your lane. Indiana Driver's Manual, p.47: “A flashing arrow board not indicating a direction either way is a signal to use caution but does not require a driver to move to another lane.”
