Passing, turning and signaling

Key points

1. Outside a city, you may pass on the right on an unobstructed highway clearly marked for 4 or more lanes.

   Source: Handbook p. 22

   “Upon any highway outside of a city with unobstructed pavement of sufficient width and clearly marked for four or more lanes of traffic.”
   Missouri Driver Guide, Handbook p. 22

2. Never pass on the right by driving onto the shoulder.

   Source: Handbook p. 22

   “In no event shall such movement be made by driving off the paved or main traveled portion of the roadway (shoulder).”
   Missouri Driver Guide, Handbook p. 22

3. Do not pass on the left within 100 feet of an intersection or railroad crossing, or where there is a solid yellow line.

   Source: Handbook p. 22

   “Approaching within 100 feet of or at any intersection or railroad grade crossing; or • There is a solid yellow line.”
   Missouri Driver Guide, Handbook p. 22

4. Do not pass on the left when your view is blocked within 100 feet of a bridge, viaduct or tunnel.

   Source: Handbook p. 22

   “The view is obstructed upon approaching within 100 feet of any bridge, viaduct, or tunnel;”

5. Speeding or passing in a state work zone brings a minimum $250 fine for a first offense and $300 for a later one.

   Source: Handbook p. 22

   “you could be fined a minimum of $250 for the first offense and a minimum of $300 for a second or subsequent offense”

6. Signal at least 100 feet before you turn.

   Source: Handbook p. 24

   “You should signal at least 100 feet before you turn so the other drivers can be ready.”
   Missouri Driver Guide, Handbook p. 24

7. Never make a U turn on a curve or near the crest of a hill where other drivers may not see you.

   Source: Handbook p. 25

   “U-turns should not be made on any curve or near the crest of a hill when your vehicle may not be seen by other drivers.”
   Missouri Driver Guide, Handbook p. 25

8. Do not use a two way left turn lane as a travel lane; you may not travel in it for more than 500 feet.

   Source: Handbook p. 26

   “Do not use this lane as travel lane (a vehicle may not travel in this lane for more than 500 feet)”
   Missouri Driver Guide, Handbook p. 26

9. If another vehicle starts to pass you, stay in your lane and do not speed up.

Numbers to know

3 questions from the Missouri practice test

1. 1. When Missouri law permits passing on the right, what roadway area may not be used to complete the pass?

   1. The left travel lane
   2. A marked turn lane
   3. The paved shoulder
   4. The lane beside the vehicle being passed
   Show answer

   The paved shoulder. Missouri permits passing on the right only in listed situations, and the guide adds an absolute boundary: the maneuver must not be made by driving off the paved or main traveled portion of the roadway, including the shoulder. The shoulder choice is therefore prohibited even when it is paved. A driver should remain on the roadway and confirm that the specific passing condition exists. Legal permission to pass on the right is not permission to leave the travel surface.

2. 2. Which city street condition is listed by Missouri as allowing a driver to pass another vehicle on the right?

   1. A narrow street with parked cars
   2. Any street during daylight
   3. An unobstructed street wide enough for two or more lines of vehicles each way
   4. A street where the center line is solid yellow
   Show answer

   An unobstructed street wide enough for two or more lines of vehicles each way. Passing on the right is listed for a city street with unobstructed pavement wide enough for two or more lines of vehicles in each direction. Width and clear pavement are both important. A narrow street with parked cars does not provide the required room, and daylight alone does not create a legal condition. A solid yellow center line describes a separate restriction and does not authorize an unsafe right side pass. Check the street's usable width before considering this exception.

3. 3. Where does the Missouri guide say a U-turn should never be made?

   1. On any two-lane road
   2. Anywhere without a traffic signal
   3. In any town
   4. On a curve or near the crest of a hill where your vehicle may not be seen
   Show answer

   On a curve or near the crest of a hill where your vehicle may not be seen. Only make a U-turn when it is safe. U-turns should not be made on any curve or near the crest of a hill when your vehicle may not be seen by other drivers, and some towns and cities do not allow U-turns at all, so check for signs. A two lane road without a curve or hill is not itself a ban, and signals are not required for a legal U-turn.
