From page 77... ...
ARKANSAS Turn arrows and ONLY word markings are used in mandatory turn lanes, but the spacing distances are not specified. A solid 4-in.-wide lane line is used to separate the turn lane from the adjacent through lane.
|
From page 78... ...
GEORGIA The top of the turn arrow nearest to the stop line is placed 25 ft from the stop line regardless of whether ONLY word markings are used. If the turn lane is formed as a new lane at the intersection, ONLY word markings are not used.
|
From page 79... ...
For lane drops, a 6-in.-wide solid lane line starts 561 ft upstream from the stop line, and turn arrows and ONLY word markings are used. The tip of the arrowhead for the turn arrow nearest to the stop line is at least 25 ft from the stop line.
|
From page 80... ...
In separate turn bays that are designed not to entrap through traffic, the dotted line portion of the lane line may be omitted, turn arrows may be used, and ONLY word markings should not be used. If turn arrows are used, the center of the turn arrow nearest to the stop line should be approximately 50 ft from the stop line.

From page 81... ...
(This is reverse reading with drivers encountering the turn arrow first and the ONLY word marking second.) If the length of the solid lane line is more than 95 ft, an alternating series of turn arrows and ONLY word markings are used, with the top of the turn arrow nearest to the stop line placed 8 ft from the stop line and with the spacing between the bottom of subsequent turn arrows or ONLY word markings being 32 to 80 ft from the top of the next turn arrow or ONLY word marking.
|
From page 82... ...
An 8-ft-long turn arrow that is similar to the turn arrow shown in Figure 3B-21 of the 2003 MUTCD is used. NORTH DAKOTA An 8-in.-wide solid lane line is used between the turn lane and the adjacent through lane.
|
From page 83... ...
The solid lane line between the turn lane and the adjacent through lane starts at the stop line and ends at the beginning of the full-width turn lane. If the length of the turn lane is less than 100 ft, only one turn arrow is used with the top placed 20 ft from the stop line, and an optional ONLY word marking may be provided with the top of the letters 35 ft upstream from the top of the turn arrow.
|
From page 84... ...
If the length of the full-width turn lane is more than 200 ft, additional sets of turn arrows and ONLY word markings are provided. At unsignalized, non-stopping approaches, the solid lane line between the turn lane and the adjacent through lane is extended and curved into the intersection until the first conflict point is reached.
|
From page 85... ...
If the length of the turn lane is more than 167 ft, two sets of turn arrows and ONLY word markings are provided (with the bottoms of the turn arrows located 32 ft upstream from the top of the letters of the ONLY word marking) with the bottom of the letters of an ONLY word marking placed 20 ft downstream from the beginning of the full-width turn lane and the turn arrow nearest to the stop line typically placed such that the top of the arrow is 20 ft from the stop line.
|
From page 86... ...
If the speed limit is 35 mph, a sequence of four turn arrows and two ONLY word markings is used in the downstream direction in the dropped lane as follows: a turn arrow, an ONLY word marking, two turn arrows, another ONLY word marking, and a turn arrow. The top of the turn arrow nearest to the stop line is placed 25 ft from the stop line.
