IA Driving Instructor common mistakes
IA Driving Instructor · Understand the traps and how to avoid them.
Treating the GDL three-stage structure as a single permit-to-license step, so the candidate cannot state which privileges and restrictions attach to instruction permit, intermediate license, and full license.
Candidates memorize one combined summary and never separate the stages, so they conflate restrictions that apply only to the intermediate stage with those on the permit.
What to do instead
Build a three-column table (permit, intermediate, full) with rows for supervising adult requirement, passenger limits, night driving limits, and time-holding requirement, and quiz yourself by covering one column at a time.
Reciting the number of supervised driving hours required before advancing but omitting the night-driving subset of those hours.
Study material often emphasizes the total hour count because it is the headline number, so the night-hours component is skipped as a detail.
What to do instead
Always state the total hours and the night hours together as one fact, and note whether night is defined by clock time or by hours after sunset.
Confusing a learner/instruction permit with an intermediate or provisional license when answering questions about who may drive alone or with non-family passengers.
Both documents look like restricted licenses to a new driver, and candidates apply the logic of one to the other.
What to do instead
Anchor each answer to the supervising-adult rule: if an adult must be present, it is a permit; if driving alone is allowed with limits, it is intermediate.
Assuming a state-issued identification card and a driver's license carry the same privileges and can be substituted for one another in eligibility questions.
Both are DMV-issued photo documents, so candidates treat them as interchangeable rather than distinguishing driving privilege from identity documentation.
What to do instead
State the defining difference in one sentence (ID card proves identity only, no driving privilege) and apply it to any question involving operating a vehicle.
Mixing up suspension and revocation, describing a suspension as permanent or a revocation as automatically restored after a fixed short period.
The terms are used loosely in everyday speech, and candidates carry that casual usage into technical questions about reinstatement.
What to do instead
Memorize the distinction as duration-based: suspension is a temporary withdrawal with a defined reinstatement path, revocation terminates the privilege and requires reapplication.
Answering OWI questions using the general adult per se threshold without checking whether a lower threshold or zero-tolerance rule applies to the driver's age or license type.
Candidates learn one number first and reuse it, missing the under-21 and commercial-vehicle variations.
What to do instead
Before answering, ask two screening questions: is the driver under 21, and is the driver operating a commercial vehicle? Then select the threshold that applies.
Treating an OWI arrest and an OWI conviction as producing identical licensing consequences, ignoring implied-consent administrative actions that can occur separately from the criminal case.
Candidates follow the criminal case timeline and overlook the administrative license action that runs on its own track.
What to do instead
Draw two parallel timelines, criminal and administrative, and note which one can affect the license before any court outcome.
Answering crash-data questions with a general impression that crashes are mostly caused by vehicle defects rather than correctly attributing the largest share to driver behaviour such as impairment, distraction, speed, and failure to yield.
Media coverage of recalls and mechanical failures is memorable, so it displaces the statistical reality of human-factor causation.
What to do instead
Memorize the human-factor dominance as a headline fact and be able to name the leading behavioural categories in order.
Giving a single following-distance rule in feet or car lengths without adjusting for speed, and stating a fixed distance as if it were speed-independent.
A memorized number feels precise and testable, so candidates lock onto it and never convert it to a time-based rule.
What to do instead
Use a time-based following rule and be able to explain why time gap scales correctly with speed while a fixed distance does not.
Describing the correct action in a skid, hydroplaning, or low-traction situation as braking hard, rather than looking and steering where you want to go while easing off the accelerator.
The instinctive response to danger is to brake, and candidates answer from instinct instead of from the physics of traction loss.
What to do instead
Rehearse the sequence aloud for each hazard (ease off accelerator, look and steer to the intended path, avoid abrupt braking or steering) until it replaces the instinctive answer.
