People charged with Vehicular Homicide and Vehicular Assault in Columbus Ohio and the central Ohio area may wonder what are the defenses to those charges. The defense for each case must be tailored to the unique facts, but there are common strategies for these cases. Those common strategies can be divided into three main categories: defenses to the allegation your driving caused the accident; defenses to the allegation you were ‘under the influence; and defenses to the allegation you were ‘over the limit’.
Defenses To The Allegation Your Driving Caused The Accident
For charges of Vehicular Homicide and Vehicular Assault, the prosecution must prove your operation of a motor vehicle caused serious physical harm or death. Therefore, the prosecution must prove your driving caused the collision. For that proof, the prosecution relies primarily on accident investigation and reconstruction. The purpose of the defenses is to show the conclusions of the accident investigation and reconstruction were incorrect because the investigation and reconstruction were flawed. Below are the top 40 defenses to the allegation your driving caused the accident:
Not all evidence collected and/or photographed
Measurements inaccurate or incorrect
Diagrams of accident scene inaccurate
Failure to investigate signage near accident site
Evidence contaminated by moving vehicles, debris or objects
Investigation conducted by officer without proper training and experience
Biased accident investigation
Eyewitness statements inaccurate due to flawed perception or memory
Client statement reported inaccurately or taken out of context
No accident reconstruction conducted
Reconstructionist lacked training and credentials
Reconstructionist had vested interest in conclusion: non-scientific conclusions
Misinterpreted exterior vehicle conditions
Misinterpreted interior vehicle conditions
No investigation of relevant vehicle recalls
Vehicle’s mechanical defect or failure caused the accident
Other driver’s intoxication caused the accident
Other driver’s recklessness or negligence caused the accident
Other driver’s medical condition caused the accident or death/serious harm
Client’s medical condition caused the accident
Reconstruction failed to properly account for sight lines and visibility
Reconstruction based on inaccurate witness’ or operators’ perspectives
Inaccurate determination of points of perception
Failure to properly evaluate human factors which may have played a role in the crash
Misinterpreted skid marks, yaw marks, gouges, and scrapes
Use of yaw marks invalid due to braking or acceleration when mark was created
Drag sled or accelerometer not used to determine road surface’s drag factor
‘Rules of thumb’ used; not scientific analysis and mathematical calculations
Calculations based on inaccurate interpretation of debris scattering
Formulas generated results which defy laws of physics
Equations excessively sensitive to minor evidence/input data inaccuracies
Equations incorrectly applied: guessing and/or adjustments made to equation
Computer-assisted formulas yielded inaccurate results due to incorrect data
Results of equations inconsistent with witness observations
Computer-generated accident simulation was one presumed scenario
Incorrect interpretation of data in reports from Crash Data Retrieval (CDR) systems
Speed in CDR Report invalid due to weather conditions.
Reconstruction ignored lack of operation evidence
Errors in medical examination led to incorrect conclusion about injury
Inaccurate analysis of debris spread and body resting place in pedestrian strike
Defenses To The Allegation You Were ‘Under The Influence’
For charges of Aggravated Vehicular Homicide and Aggravated Vehicular Assault based on the charge of OVI ‘Impaired’, the prosecution must prove you operated a vehicle ‘under the influence’ of alcohol and/or drugs. To prove you were ‘under the influence’, the prosecution introduces testimony of witnesses; primarily police officers. The purpose of the defenses is to show the witness observations do not prove impairment. Below are the top 40 defenses to the allegation you were ‘under the influence’:
Driving: lack proof you were the operator of the vehicle
Alcohol or drugs consumed after the accident
Interaction with officer: no odor of alcohol
Interaction with officer: no slurred speech
Interaction with officer: no glassy/bloodshot eyes
Interaction with officer: no admission of consuming alcohol or drugs
Interaction with officer: no problem with mental faculties
Interaction with officer: no problem with physical coordination
Interaction with officer: no problem with divided attention
No evidence of alcohol or drugs/drug paraphernalia in vehicle
Field sobriety tests: not admissible due to lack of compliance with training manual
Field sobriety tests: not reliable due to faulty administration
Field sobriety tests: good performance from common sense perspective despite observation of technical ‘clues’
Field sobriety tests: unrelated to impaired driving ability
Field sobriety tests: medical condition affected ability to perform tests
Field sobriety tests: non-standardized tests have no correlation with intoxication
Field sobriety tests: non-standardized tests inadmissible under rules of evidence
Drug recognition evaluations: 12-steps not properly implemented
Drug recognition evaluations: failure to comply with certification requirement
Drug recognition evaluations: components unrelated to driving impairment
No problems with balance
No problems with coordination
No problems following instructions
Arrest unlawful: officer did not have probable cause to believe driver was under the influence
Arrest unlawful: officer outside jurisdiction
Statements made to officer inadmissible due to lack of Miranda warnings
Statements made to officer inaccurately reported or taken out of context
Fatigue has symptoms which can be mistaken for intoxication
Medical conditions may have symptoms which can be mistaken for intoxication
Ambien use negates the actus reus requirement; the act of driving is involuntary
Confirmation bias: officer jumped to conclusion and looked for evidence to confirm conclusion
Officer discounted evidence inconsistent with intoxication
Officer under pressure to make arrest
Refusal of chemical test: no advice or improper advice given regarding consequences of refusing test
Refusal of chemical test: no notification of right to appeal or independent chemical test
Refusal of chemical test: officer’s claim of refusal inaccurate
Refusal of chemical test: inability to take test is not a refusal
Refusal of chemical test: enhancement of penalty improper because prior OVI convictions ‘invalid’
Evidence destroyed after requested by defense
Speedy trial rights violated
Defenses To The Allegation You Were ‘Over The Limit’
For charges of Aggravated Vehicular Homicide and Aggravated Vehicular Assault based on the charge of OVI ‘Per Se’, the prosecution must prove you operated a vehicle with a prohibited concentration of alcohol and/or drugs in your blood, urine, or breath. To prove your alcohol and/or drug level was ‘over the limit’, the prosecution introduces results of blood, urine, or breath tests. The purpose of the defenses is to exclude the tests from evidence or show why the test results were inaccurate. Below are the top 40 defenses to the allegation you were ‘over the limit’:
