THOMASVILLE, Ala. — Thomasville High School students spent Monday learning what impairment feels like before they ever get the chance to experience it for real, working through field sobriety tests and a driving exercise while wearing goggles designed to simulate the effects of alcohol.
The exercise was part of the school’s driver’s education class. It began inside the school gym, where students participated in field sobriety tests, before moving outdoors to simulate driving while legally impaired.
Students used a golf cart for the outdoor portion, allowing them to experience how impaired judgment and coordination affect the ability to operate a vehicle.
“We had a great learning experience in class today,” said driver’s education instructor Robby Carpenter.
How the Goggles Work
Impairment simulation goggles use specially designed lenses to distort what the wearer sees, reproducing several of the visual and perceptual effects associated with alcohol impairment.
The distortion typically produces delayed reaction time, reduced depth perception, difficulty judging distance and speed, impaired eye-hand coordination, and a loss of balance. Different models simulate different blood alcohol concentration ranges, and some simulate the additional difficulty of nighttime impairment.
What the goggles cannot reproduce is the part of impairment that matters most: the loss of judgment about whether one is impaired. A student wearing goggles knows they are compromised and compensates accordingly. A driver who has been drinking frequently does not.
That limitation is well understood by instructors who use the equipment, and it is one reason the exercise is typically paired with discussion rather than presented on its own.
Why the Field Sobriety Portion Matters
The indoor segment — field sobriety tests in the gym — teaches something the driving exercise does not.
Standardized field sobriety tests are the battery of assessments law enforcement officers use during a traffic stop when impairment is suspected. The standardized battery includes horizontal gaze nystagmus, the walk-and-turn, and the one-leg stand. Officers are trained to administer them in a specific way and to look for specific indicators.
Students attempting a walk-and-turn or a one-leg stand while wearing impairment goggles discover directly that these are not tests one can talk one’s way through. The physical indicators an officer is trained to observe are not subtle, and they are not within the subject’s control.
That is a useful thing for a sixteen-year-old to learn in a gymnasium rather than on a roadside.
The Law Students Are Driving Under
Alabama’s impaired driving law treats drivers under 21 very differently from adult drivers, and the distinction is one many young drivers do not fully appreciate.
For drivers 21 and older, the per se legal limit is a blood alcohol concentration of 0.08 percent.
For drivers under 21, Alabama has a zero tolerance provision setting the threshold at 0.02 percent. That figure is low enough to be reached by a very small quantity of alcohol.
Alabama also has an implied consent law: by driving on the state’s roads, a driver is deemed to have consented to chemical testing when lawfully arrested for impaired driving. Refusing the test carries its own license suspension, separate from any penalty for the underlying offense.
The graduated driver licensing system adds another layer for teen drivers, with restrictions on nighttime driving and on the number of passengers permitted, phased out as a driver gains experience and age.
Why This Age Group
Crash risk for newly licensed drivers is elevated in a way that no other stage of driving matches, and the reason is not primarily recklessness.
It is inexperience. Driving is a skill that improves with exposure to varied conditions, and a new driver has not yet encountered most of the situations that require rapid, correct responses. Hazard recognition — the ability to identify a developing problem before it becomes an emergency — develops over thousands of miles.
Adding impairment to inexperience compounds both. An experienced driver has automated responses that survive some degradation. A new driver is still performing those tasks consciously, and impairment degrades exactly the cognitive resources that consciousness requires.
The other factor specific to this age group is passengers. Crash risk for teen drivers rises measurably with each additional teen passenger in the vehicle, which is why graduated licensing systems restrict passengers rather than trusting drivers to manage the distraction.
What the Research Says About Programs Like This
Honesty about the evidence is warranted here. Research on impairment simulation exercises has produced mixed findings about whether they change behavior over the long term. Studies of scared-straight-style interventions in other contexts have sometimes found no effect or even counterproductive results.
What tends to distinguish effective programs is integration. An exercise embedded in a driver’s education course, delivered alongside instruction on the law, on decision-making and on practical alternatives, performs better than a one-off assembly presentation delivered in isolation.
The Thomasville exercise is of the former type — part of a driver’s education class rather than a standalone event.
The other element research consistently supports is planning. Students who have decided in advance what they will do — who they will call, what the arrangement is — make better decisions than students who intend to decide in the moment. That is a conversation for families as much as for classrooms.
The Practical Conversation
Highway safety organizations consistently recommend that parents and teen drivers establish an explicit understanding: that a call for a ride, from any situation, will be answered without an argument in that moment.
The reason the arrangement is framed that way is that the alternative is a teenager weighing the consequences of calling against the consequences of driving — and making that calculation while impaired, or while a friend is.
The other point worth making to a class of new drivers is that impairment is not limited to alcohol. Cannabis, prescription medications including some prescribed for anxiety or pain, over-the-counter antihistamines, and fatigue all degrade driving ability. Alabama’s impaired driving statute is not confined to alcohol.
Driver’s Education in Alabama
Driver’s education is offered in many Alabama high schools as an elective, and it occupies an unusual position in the curriculum: it is one of the few courses whose subject matter carries an immediate risk of death for students in the room.
Motor vehicle crashes remain among the leading causes of death for American teenagers. That statistic has improved substantially over decades through vehicle safety design, graduated licensing and enforcement, but the underlying exposure has not changed — young people begin operating vehicles at an age when their experience is minimal.
Exercises like the one at Thomasville High School are one piece of a response to that reality. They work best as part of a sustained conversation rather than a single memorable afternoon.
