Where no signs or markings say otherwise, Delaware has default rules: keep right, pass on the left, turn from the nearest lane, and never back up or stop in a travel lane. And always signal 300 feet ahead.

300 ft

Distance you must signal before your intended action

Handbook p. 79 ↗

Know the rule

Signal by hand or turn signal whenever you intend to stop, turn or change lanes.

Handbook p. 79 ↗

Know the rule

Overtake other vehicles on the left, only at a safe distance, and return to the right only when safely clear. A vehicle being overtaken must give way to the right and not speed up until fully passed.

Handbook p. 79 ↗

Know the rule

When passing a cyclist, leave at least three feet of clearance at all times, and on multi-lane roads move to the adjacent lane whenever possible.

Handbook p. 79 ↗

Know the rule

Never back up in a travel lane except to parallel park or, if necessary, to exit a driveway. If you miss your turn or exit, go on to where you can safely turn around.

Handbook p. 85 ↗

Know the rule

Don't stop in a travel lane for any reason (confusion, breakdown, letting out a passenger). Keep moving until you can safely pull off.

Handbook p. 85 ↗

Know the rule

With two or more lanes in your direction, stay in the right lane except to pass. With three or more lanes and heavy entering and exiting traffic, use the center lane.

Handbook p. 85 ↗

Know the rule

Passing a left-turning vehicle on the right is legal in Delaware—even using the shoulder—but it's very crash-prone and requires great caution.

Handbook p. 85 ↗

Turning where no signs or markings control it:

  • Turn from the lane closest to your direction into the lane closest to the one you came from
  • Right turns: don't swing wide to the left before or while turning
  • Left turns: don't cut the corner, but leave room for oncoming vehicles turning left
  • Two or more turn lanes: stay in your lane throughout the turn
Handbook p. 85 ↗

Know the rule

Median crossings: if marked for emergency vehicles only, you may not cross there. Otherwise keep to the right, treating the median opening like a roadway.

Handbook p. 86 ↗
Diverging diamond interchange: correct vs incorrect left turn (composite)
Median crossings: incorrect and correct

Put it into practice

You're turning right into a shopping center driveway. Start signaling at least 300 feet before the turn, stay close to the right, and don't swing wide into the left lane first.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

Before turning, changing lanes, or stopping, Delaware law requires you to signal for at least
  1. 300 feet
  2. 100 feet
  3. 200 feet
  4. 500 feet

Answer: 300 feet

You must signal continuously for at least 300 feet before turning.

Handbook p. 79 ↗
When passing another vehicle, Delaware law states you should overtake
  1. on the right whenever the left lane is occupied
  2. on the left, returning right once clear
  3. on either side, whichever is faster
  4. only on divided highways

Answer: on the left, returning right once clear

Vehicles must overtake others on the left at a safe distance and return to the right only when safely clear.

Handbook p. 79 ↗
On a road with two or more lanes traveling the same direction, you should generally
  1. stay in the left lane unless turning right
  2. use whichever lane has less traffic
  3. stay in the right lane except to pass
  4. stay in the left lane to leave room for merging

Answer: stay in the right lane except to pass

On multi-lane roads, drivers should stay in the right lane except when passing.

Handbook p. 85 ↗
Passing a left-turning vehicle on the right in Delaware is
  1. illegal
  2. legal only on the interstate
  3. legal only if the turning vehicle signals
  4. legal, but requires great caution

Answer: legal, but requires great caution

Delaware law allows passing left-turning vehicles on the right, but this is a crash-prone maneuver requiring extreme caution.

Handbook p. 85 ↗
When making a right turn, you should avoid
  1. signaling before the turn
  2. swinging wide to the left before turning
  3. slowing down before the turn
  4. turning into the lane closest to the curb

Answer: swinging wide to the left before turning

Swinging wide to the left before a right turn can confuse drivers behind you into thinking you're changing lanes or turning left.

Handbook p. 85 ↗
You must maintain your turn signal for at least 300 feet before turning under Delaware law.
  1. True
  2. False

Answer: True

Delaware law requires signaling continuously for at least 300 feet before a turn.
