In the walk and turn test, the subject is required to take nine heel-to-toe steps in a straight line, turn around in a prescribed manner, and then return nine heel-to-toe steps back along the line. This means that the subject must complete a total of nine heel-to-toe steps in both directions, ensuring that they maintain balance and coordination throughout the test.

The Modified Romberg Balance is not a validated field sobriety test. The other three options, the One leg stand, Walk and turn, and Horizontal Gaze Nystagmus, are all recognized and validated field sobriety tests used by law enforcement to assess a person's level of impairment due to alcohol or drugs. The Modified Romberg Balance, however, is not widely accepted or recognized as a standard field sobriety test.

The word "nystagmus" refers to the involuntary jerking of the eyes. This condition causes rapid and uncontrollable eye movements, which can be horizontal, vertical, or rotational. Nystagmus can be caused by various factors, such as neurological disorders, inner ear problems, or certain medications. It can affect vision and balance, and may be a symptom of an underlying medical condition.

The legal limit for Blood Alcohol Concentration (BAC) is .08. This means that if a person's BAC is .08 or higher, they are considered legally intoxicated in many jurisdictions. This limit is used to determine if a person is impaired and unfit to operate a vehicle. It is important to stay below this limit to ensure safety on the roads and avoid legal consequences such as fines, license suspension, or even imprisonment.

The walk and turn test is a standardized field sobriety test used to assess a person's coordination and balance. The clues in this test typically include starting too soon, stopping while walking, not touching heel-to-toe, stepping off the line, using arms to balance, improper turn, and incorrect number of steps. However, doing a celebration dance upon completion of the test is not considered a clue in the walk and turn test.

The HGN (Horizontal Gaze Nystagmus) Medical Impairment Assessment checks for all of the mentioned factors. It involves checking the eyes for equal pupil size, resting nystagmus, and equal tracking. These assessments are important in determining any impairment or abnormality related to eye movements, which can be indicative of certain medical conditions or impairments.

The correct answer is 6. In the one leg stand test, the person's foot should be 6 inches off the ground. This test is often used in field sobriety tests to assess a person's balance and coordination. By lifting one leg and maintaining balance for a specific duration, it can indicate impairment or sobriety. Having the foot 6 inches off the ground ensures that the person is challenging their balance and is a standardized measurement for performing the test accurately.

Ethanol is the correct answer because it is the type of alcohol commonly found in alcoholic beverages. Methanol, isopropanol, and butyl are different types of alcohols that are not typically used in the production of alcoholic drinks. Ethanol is the main psychoactive ingredient in alcoholic beverages and is responsible for the intoxicating effects when consumed.

The walk and turn test is an example of a divided attention test. This test requires individuals to simultaneously perform physical movements, such as walking in a straight line, while also following verbal instructions. By dividing their attention between these two tasks, it becomes more difficult for someone who is intoxicated to successfully complete the test. Therefore, the walk and turn test is commonly used by law enforcement as a means to assess a person's level of intoxication.

The "big four" points that you must make sure the person taking the test knows are to keep their arms at their sides, watch their feet at all times, count out loud, and not stop until they complete the test.

In the detection phase one, the police officer's main decision is to determine whether they have sufficient grounds to stop the vehicle. This decision is crucial as it determines whether the officer can proceed with further actions such as requesting a chemical test or instructing the driver to exit the vehicle. Without sufficient grounds to stop the vehicle, the officer may not have the authority to take any further actions.

The three phases of detection are vehicle in motion, personal contact, and pre-arrest screening. "Going to jail" is not one of the phases of detection.

A good, structured field sobriety test is simple and divides the subject's attention. Dividing the subject's attention is important because it helps assess their ability to multitask and perform different tasks simultaneously. By dividing their attention, the test can evaluate their coordination, balance, and cognitive abilities, which are all crucial indicators of sobriety.

In the one leg stand test, the individual is required to stand on one leg and maintain balance for a certain period of time. The clues in this test are behaviors that indicate impairment or inability to maintain balance. Sways while balancing, uses arms to balance and hopping, and puts foot down are all clues that suggest difficulty in maintaining balance. However, taking too many steps is not a clue in this test as it does not directly relate to balance.

The two stages to the one leg stand are the instruction stage and the balance and counting stage. During the instruction stage, the individual is given clear instructions on how to perform the test. In the balance and counting stage, the person is required to lift one leg off the ground and maintain their balance while counting out loud for a specific duration of time. These two stages are crucial in assessing an individual's ability to maintain balance and coordination.

During Detection Phase Three, the police officer's principal decision is whether or not to arrest the operator for DWI (Driving While Intoxicated). This decision is crucial as it determines whether legal action will be taken against the individual based on suspicion of driving under the influence of alcohol or drugs. The officer must consider various factors such as the driver's behavior, physical appearance, and the results of any field sobriety tests conducted. Ultimately, this decision will impact the legal process and potential consequences for the individual involved.

During the Detection Phase Two, the officer's principal decision usually revolves around whether or not to instruct the driver to exit the vehicle. This decision is crucial as it allows the officer to further assess the driver's behavior, physical condition, and potential impairment. By asking the driver to exit the vehicle, the officer can gather more evidence to determine if there are sufficient grounds to proceed with a DUI investigation or arrest.

The correct answer is "Instruction stage and walking stage". In the instruction stage, the person is given clear and specific instructions on how to perform the walk and turn test. This stage is important to ensure that the person understands the task correctly. In the walking stage, the person is required to take a series of steps in a straight line, heel-to-toe, while keeping their arms at their sides. This stage is used to assess the person's balance, coordination, and ability to follow instructions accurately.

The correct answer is "distinct and disstained nystagmus at maximum deviation". The HGN test, also known as the Horizontal Gaze Nystagmus test, is a field sobriety test used to detect impairment due to alcohol or drugs. The three clues in the HGN test are lack of smooth pursuit, distinct and sustained nystagmus at maximum deviation, and onset of nystagmus prior to 45 degrees. The answer choice "distinct and disstained nystagmus at maximum deviation" is not one of the three clues in the HGN test.

The person taking the one leg stand test should be counting like "one thousand one, one thousand two, one thousand three, one thousand four" because this counting method ensures that each count is clear and distinct, allowing the person to maintain their balance and focus on the task at hand. The use of "one thousand" before each number helps to provide a consistent rhythm and pacing for the count.

During the one leg stand test, the subject is instructed to count out loud until they are told to stop. This instruction is given to ensure that the subject maintains their focus and concentration during the test. By counting out loud, it helps the subject to stay engaged and avoid any distractions that may affect their balance or performance. It also allows the test administrator to monitor the subject's ability to follow instructions accurately.

If the person you are testing is wearing shoes with a heel higher than 2 inches, you must give them the chance to remove their shoes. This implies that there is a specific height limit for the heels that are allowed during the testing. If the person exceeds this limit, they need to remove their shoes to ensure fairness and consistency in the testing process.

The "illegal per se" law makes it an offense to operate a vehicle while having a statutorily prohibited blood alcohol content. This means that if a person's blood alcohol content exceeds the legal limit set by the statute, they are automatically considered to be in violation of the law, regardless of whether they are actually impaired or under the influence of alcohol or drugs. This law focuses solely on the blood alcohol content level and does not require proof of impairment.

There are three validated clues for HGN testing.

In the Horizontal Gaze Nystagmus (HGN) test, there are six possible clues that can be assessed. However, not all six clues are necessarily present in every case, and law enforcement officers typically look for three validated clues to determine impairment accurately. These three clues are the most reliable indicators of impairment in the HGN test. So, while there are six possible clues, the three validated clues are the most significant indicators of impairment.

Horizontal Gaze Nystagmus (HGN) is one of the standardized field sobriety tests used by law enforcement to detect impairment. There are six validated clues for Horizontal Gaze Nystagmus:

Lack of Smooth Pursuit: Inability to smoothly track a moving object.

Distinct and Sustained Nystagmus at Maximum Deviation: Involuntary jerking of the eyes at maximum deviation.

Onset of Nystagmus Prior to 45 Degrees: Nystagmus occurs before the eyes move 45 degrees to the side.

These clues are observed in both eyes, resulting in a total of six clues. The presence of these clues may indicate impairment due to alcohol or drugs.
