7.2 Right-of-Way Rules and Intersection Management

7.2 Right-of-Way Rules & Intersection Management

Intersections represent the highest-risk conflict zones in the highway transportation system. In Maryland, intersection navigation is governed by the statutory right-of-way framework codified under the Maryland Annotated Code, Transportation Article, Title 21, Subtitle 4 (TR § 21-401 et seq.) and Subtitle 5 (Pedestrians' Rights and Rules, TR § 21-501 et seq.).

A fundamental legal and pedagogical principle in Maryland driver education is that right-of-way is given, never taken. Maryland vehicle law specifies which roadway user must yield the right-of-way under given geometric and traffic conditions; no statute grants any driver an absolute, unconditional right to proceed. Certified instructors must instill this philosophy in novice drivers, teaching them to verify that conflicting traffic is yielding before asserting movement.

Uncontrolled Intersections & Open Crossings (TR § 21-401)

An uncontrolled intersection is an intersection lacking traffic signals, stop signs, yield signs, or police control. While common in residential subdivisions and rural areas, they present severe collision hazards due to sight obstructions (blind corners, overgrown vegetation, parked vehicles).

Maryland Statutory Rules for Uncontrolled Intersections

1. Vehicle Already in Intersection: A driver approaching an uncontrolled intersection must yield the right-of-way to any vehicle that has already entered the intersection from a different highway (TR § 21-401(a)).
2. Simultaneous Arrival (The Vehicle on the Right Rule): If two vehicles approach or enter an uncontrolled intersection from different highways at approximately the same time, the driver of the vehicle on the left must yield the right-of-way to the vehicle on the right (TR § 21-401(b)).
3. Instructional Visual Search: Instructors must train students to execute a mandatory Left-Center-Right-Left visual scan when approaching open intersections, covering the brake to reduce reaction time if conflicting vehicles fail to yield.

Four-Way & Multi-Way Stop Controlled Intersections (TR § 21-707)

Multi-way stop intersections (indicated by a standard STOP sign with a supplemental "ALL WAY" or "4-WAY" plaque) establish clear sequential right-of-way rules:

+-----------------------------------------------------------------------------------------+
|                        FOUR-WAY STOP RIGHT-OF-WAY HIERARCHY                             |
|                                                                                         |
|  RULE 1: First-in, First-out  =====> Vehicle that stops completely first proceeds first |
|  RULE 2: Simultaneous Arrival =====> Vehicle on the LEFT yields to vehicle on the RIGHT |
|  RULE 3: Opposing Simultaneous ====> Turning vehicles yield to straight-through traffic|
|  RULE 4: Left Turn vs. Right  =====> Left-turning vehicle yields to right-turning vehicle|
+-----------------------------------------------------------------------------------------+

Step-by-Step Priority Breakdown

• First to Arrive / First to Stop: The vehicle that arrives and comes to a complete stop first has the primary right-of-way to proceed through the intersection.
• Simultaneous Arrival (Side-by-Side): When two vehicles reach the stop line and complete their stops at the exact same time, the driver on the left must yield to the driver on the right.
• Simultaneous Arrival (Opposing Directions):
  • If both vehicles intend to travel straight, both may proceed simultaneously.
  • If one vehicle intends to travel straight and the opposing vehicle signals a left turn, the left-turning vehicle must yield to the straight-through vehicle.
  • If one vehicle signals a right turn and the opposing vehicle signals a left turn into the same receiving roadway, the left-turning vehicle must yield to the right-turning vehicle.

Specialized Intersection Configurations & Entry Rules

1. T-Intersections (TR § 21-401.1)

At a T-intersection (where a terminating roadway intersects a through highway without traffic control devices):

• The driver traveling on the terminating roadway (the stem of the "T") must yield the right-of-way to all traffic approaching on the through highway.
• Through traffic on the continuous road has priority over turning vehicles entering from the terminating street.

2. Entering Highway from Private Driveways, Alleys & Parking Lots (TR § 21-404)

Under Md. Code Ann., Transp. § 21-404, a driver emerging from an alley, private driveway, building exit, or commercial parking lot onto a public highway must:

1. Bring the vehicle to a complete stop immediately prior to driving onto a sidewalk or sidewalk area extending across the alleyway or driveway;
2. Yield the right-of-way to any pedestrian approaching along the sidewalk; and
3. Upon entering the roadway, yield the right-of-way to all vehicles approaching on the roadway.

3. Left-Turn Right-of-Way Rules (TR § 21-402)

Under TR § 21-402(a), a driver intending to turn left within an intersection or into an alley, private road, or driveway must yield the right-of-way to any vehicle approaching from the opposite direction that is within the intersection or so close as to constitute an immediate hazard.

Instructor Hazard Alert: The Left-Turn Trap & Gap Judgment

Left turns across oncoming traffic account for a disproportionate share of severe adolescent driver collisions. Instructors must teach novice drivers to evaluate gaps in opposing traffic based on speed and distance (requiring a minimum 4- to 6-second gap in residential traffic and 6- to 8-second gap on multi-lane arterials). When waiting to turn left, students must keep their front wheels pointed straight ahead; if rear-ended while wheels are turned left, the vehicle will be shoved into the path of oncoming traffic.

Modern Roundabouts and Traffic Circles (governed by TR § 21-403 and general right-of-way rules)

Modern roundabouts are circular intersections engineered with specific geometric features to promote continuous, low-speed traffic flow and eliminate high-angle, right-angle, and head-on collisions.

                    [ MULTI-LANE ROUNDABOUT NAVIGATION ]

                             Exit North
                                 ▲
                                 │
                           ┌─────┴─────┐
                           │ Circulating│
        Exit West ◄────────┤  Counter-  ├────────► Exit East
                           │  Clockwise │
                           └─────┬─────┘
                                 │
                                 ▲
                            Entry South
               [ LANE SELECTION: Right = Right/Thru | Left = Thru/Left/U-Turn ]

Operational Rules for Navigating Roundabouts

1. Yield on Entry: Drivers entering a roundabout must yield the right-of-way to circulating traffic already inside the circle (approaching from the left) and to pedestrians in entry crosswalks.
2. Counter-Clockwise Circulation: All traffic circulates to the right of the central island in a counter-clockwise direction.
3. Pre-Entry Lane Selection (Multi-Lane Roundabouts):
   • Right Lane: Use for executing a Right Turn (first exit) or traveling Straight Through (second exit).
   • Left Lane: Use for traveling Straight Through (second exit), executing a Left Turn (third exit), or making a Full U-Turn (returning to original roadway).
4. In-Circle Lane Discipline: Drivers must never change lanes, pass, or stop inside a roundabout. If a driver misses their desired exit, they must continue around the circle until the exit is reached again.
5. Exit Signaling: Drivers must activate their right turn signal when passing the exit immediately preceding their intended exit to communicate their departure to waiting entry traffic.
6. Truck Aprons: Large commercial vehicles may mount the raised concrete truck apron encircling the central island. Passenger vehicles must never attempt to pass commercial trucks inside a roundabout.

Emergency Vehicles and Authorized Responders (TR § 21-405)

Under Maryland law, the approach of an authorized emergency vehicle (police, fire, ambulance, rescue squad) executing an emergency response creates an immediate statutory duty for all surrounding motorists.

Mandatory Driver Actions

• Visual & Audible Triggers: Upon the immediate approach of an emergency vehicle displaying flashing red or blue emergency lights and sounding an audible siren, bell, or exhaust whistle:
  1. The driver must immediately yield the right-of-way;
  2. Drive to a position parallel to, and as close as possible to, the right-hand edge or curb of the roadway, clear of any intersection; and
  3. Bring the vehicle to a complete stop and remain stopped until the authorized emergency vehicle has passed, unless otherwise directed by a police officer.
• Intersection Clearance: If a driver is already inside an intersection when an emergency vehicle approaches, they must proceed completely through the intersection before pulling over to the right curb and stopping.

Maryland Pedestrian & Vulnerable User Right-of-Way (TR § 21-502)

Pedestrians are among the most vulnerable participants in the highway transportation system. Maryland enforces strict statutory protections to eliminate pedestrian fatalities:

Maryland Crosswalk Law (TR § 21-502(a))

Under Md. Code Ann., Transp. § 21-502(a)(2), the driver of a vehicle shall stop and remain stopped for a pedestrian crossing the roadway within any marked or unmarked crosswalk at an intersection if the pedestrian is:

1. On the half of the roadway on which the vehicle is traveling; OR
2. Approaching so closely from the opposite half of the roadway as to be in danger (statutorily interpreted as being within one lane of the driver's half of the roadway).

+-----------------------------------------------------------------------------------------+
|                        MARYLAND PEDESTRIAN STOPPING RULE                                |
|                                                                                         |
|  [ Opposing Lane 2 ]  ===>  Pedestrian Crossing                                         |
|  [ Opposing Lane 1 ]  ===>  Within 1 Lane of Divider  ===>  [ DRIVER MUST STOP & REMAIN ]
|  ===================  === CENTERLINE / MEDIAN ===   ===>  [ STOPPED UNDER § 21-502  ]
|  [ Driver's Lane 1 ]  ===>  Driver Approaches Lane 1  ===>  [ DO NOT PASS STOPPED CARS ]
+-----------------------------------------------------------------------------------------+

Prohibition on Passing Stopped Vehicles (TR § 21-502(c))

Whenever any vehicle is stopped at a marked crosswalk or at any unmarked crosswalk at an intersection to permit a pedestrian to cross the roadway, the driver of any other vehicle approaching from the rear shall not overtake and pass the stopped vehicle. Passing a vehicle stopped for a pedestrian is a severe moving violation and a primary cause of multi-threat pedestrian crashes.

Visually Impaired Pedestrians (TR § 21-511)

Under TR § 21-511, a driver must bring their vehicle to a complete stop and yield the right-of-way whenever a blind or visually impaired pedestrian is crossing the roadway guided by a trained guide dog or carrying a metallic or white cane (or white cane tipped with red).
