Read turning backing and starting factors

By Jacob Alford

A turning dispute can involve the starting lane, signal, turn path, available space or danger to another road user. Backing and starting from a stopped position have their own questions. Vehicle size may matter to what was practicable, but it does not answer every duty. Match photographs and video to the particular maneuver.

Questions this group helps answer:

• What is unsafe backing?
• Can a driver signal correctly and still turn unsafely?
• What is the difference between a wide right turn and a turn from the wrong lane?
• What does cutting a left corner mean?
• Do turn arrows change the usual path?
• Does improper start cover a stopped vehicle that was not parked?

3. Backed without safety

Meaning in the report: An unsafe backing movement contributed to the crash.

What needs explaining: Identify the backing movement and the danger it created, not merely that a vehicle was reversing. What could the driver see, where were other road users, and was there time and space to back safely?

Limits and qualifications: A backup camera or warning sensor does not settle whether the movement was safe.

Related law and scope: Backing must be safe and without interference with other traffic. Subsection (b) separately forbids backing on a shoulder or roadway of a limited-access or controlled-access highway.

Sources: TxDOT definition, page 136; Transportation §545.415(a); Transportation §545.415(b) (related provision).

Further care: A crash does not by itself resolve whether the backing could be made safely; distinguish a moving backing vehicle from a vehicle already stationary.

17. Disregard turn marks at intersection

Meaning in the report: The vehicle did not follow the course directed by official traffic-control devices in or near an intersection.

What needs explaining: Identify the specific turn marking or control and how the departure contributed. What did the lane arrows, signs and turn-path markings require on the crash date?

Limits and qualifications: Do not substitute an assumed customary turn path for an actual controlling device.

Related law and scope: Section 545.101(e) authorizes an official device in or adjacent to an intersection to require a turn course different from the default paths in (a)–(d). Section 544.004 supplies the general obligation to obey an applicable official device.

Sources: TxDOT definition, page 137; Transportation §545.101; Transportation §544.004(a)–(b) (related provision).

Further care: The markings/device and lawful directed course matter. The manual’s section citation is not itself proof that any preferred path was legally required.

28. Failed to signal or gave wrong signal

Meaning in the report: A missing, incorrect or misleading signal contributed to the crash.

What needs explaining: Identify the movement requiring the signal and whether the signal was omitted or wrong. What maneuver was intended, what signal was given, and when could other road users see it?

Limits and qualifications: The rules for turning, lane changes, stopping and hand or mechanical signals are not identical.

Related law and scope: Section 545.104(a) covers turns, lane changes and starts from parked; (b) requires a continuous signal for at least the last 100 feet before a turn; (c) restricts misleading one-sided/courtesy signals. Section 545.105 requires a stop/deceleration signal when an opportunity exists. Section 545.106 prescribes hand/arm or lamps and the vehicle-size cases requiring lamps.

Sources: TxDOT definition, page 138; Transportation §545.104; Transportation §545.105; Transportation §545.106.

Further care: The 100-foot rule expressly addresses turns; do not automatically apply it to every lane change. The opportunity qualification matters for stopping signals.

49. Improper start from a stopped standing or parked position

Meaning in the report: An unsafe start or movement from a stopped, standing or parked position contributed.

What needs explaining: The current definition covers all three positions, not just parking. From what position did the vehicle move, and what traffic or people were exposed to danger?

Limits and qualifications: Do not confine the present code to a parking space just because a shortened table label says parked.

Related law and scope: A stopped, standing or parked vehicle may not begin moving unless the movement can be made safely.

Sources: TxDOT definition, page 140; Transportation §545.402.

Further care: The full statute and factor definition cover stopped, standing and parked positions. The manual p. 133 summary table shortens this to parked position; the current standalone code sheet and embedded manual p. 20 use the full label.

63. Turned improperly cut corner on left

Meaning in the report: At an intersection, a left turn began or ended too soon and contributed.

What needs explaining: Identify the actual approach and path through the intersection. Did the vehicle cut across the intended turn path or enter the opposing side too early?

Limits and qualifications: The position and path rules must be applied to the intersection layout and controlling devices.

Related law and scope: Approach in the extreme lawful left lane; after entering the intersection turn left and leave in a lane lawfully available in the direction of travel. Subsection (c) adds the practicable path left of intersection center for two-way traffic; (e) allows official devices to direct another course.

Sources: TxDOT definition, page 141; Transportation §545.101(b); Transportation §545.101(c),(e) (related provision).

Further care: Do not invent a universal nearest-left-lane landing requirement: (b)(2) says a lane lawfully available. The actual markings and geometry matter.

64. Turned improperly wide right

Meaning in the report: A right turn at an intersection was not as near as practicable to the right curb or edge, short of turning from the wrong lane.

What needs explaining: The manual distinguishes a wide turn from code 65’s wrong-lane turn. What space was practically available given the vehicle, road design and other traffic?

Limits and qualifications: As closely as practicable is not a zero-tolerance curb-hugging rule. Identify the space and road conditions that affected the turn.

Related law and scope: Both approach and right turn must be as closely as practicable to the right curb/roadway edge, subject to an officially directed alternative course under (e).

Sources: TxDOT definition, page 141; Transportation §545.101(a); Transportation §545.101(e) (related provision).

65. Turned improperly wrong lane

Meaning in the report: A right or left intersection turn was made from the wrong lane and contributed.

What needs explaining: Determine the designated or legally required turn lane. What lane did the vehicle begin from, and what signs or markings changed the usual rule?

Limits and qualifications: Do not confuse the origin lane with the width or end point of the turn.

Related law and scope: Apply (a) right-turn approach/path, (b) left-turn lane approach and lawful exit, (c) practicable intersection path, (d) one-way-to-one-way left turns, and (e) official alternative turn courses.

Sources: TxDOT definition, page 141; Transportation §545.101.

Further care: The factor alone does not identify which subsection was violated. Do not assume the conventional turn rule overrides posted lane arrows or a lawful special course.

66. Turned when unsafe

Meaning in the report: A turn or departure from a direct course was made when it could not be done safely.

What needs explaining: The definition covers the safety of the movement, even where another turn-path code does not fit. What hazard made the turn unsafe, and was it reasonably observable before movement?

Limits and qualifications: Signaling does not itself establish that a turn could safely be made.

Related law and scope: Turning into a private road/driveway, turning from a direct course, or moving right/left on a roadway is prohibited unless safe.

Sources: TxDOT definition, page 142; Transportation §545.103.

Further care: A signal alone does not make an unsafe turn permissible; factor 66 and factor 28 identify different issues.
