Understanding the Glasgow Coma Scale After a Car Accident in Virginia
How the score works, what a low or high score can and cannot tell you, and why a head injury needs a medical evaluation even when the score looks normal.
Published November 5, 2026
The Glasgow Coma Scale is a bedside test that scores how a person responds after a head injury. After a car accident, it is often one of the first numbers a family hears. This page explains what the scale measures, how its parts add up, and why one reading does not tell the whole story.
What the Glasgow Coma Scale Measures
The Glasgow Coma Scale, often shortened to GCS, measures a person’s level of consciousness and responsiveness. It uses reactions that a clinician can watch and record, such as whether a person opens their eyes or follows a command. It does not rely on a scan.
Doctors built the scale so that emergency and hospital staff could describe a patient the same way. A shared, repeatable method helps different people on a care team understand the same condition. Doctors use it for head injuries from many causes, including crashes, falls and assaults.

How the Three Scores Add Up to a Total
The scale looks at three separate responses. These are eye opening, verbal response and motor response. Each one gets its own score, and the three scores are added together to make one total.
A low score in one category tells you the person was responding less in that area at the time of the test. For example, a low eye-opening score means the person did not open their eyes on their own or when spoken to or touched. A low verbal score points to limited speech or confusion. A low motor score points to limited movement when asked to move.
A total is a snapshot. It shows how the person responded at one moment. It is not a permanent label, and it can change as the person’s condition changes.
How Doctors Group Scores Into Mild, Moderate and Severe
Doctors often group the total into mild, moderate or severe ranges. These groups describe how serious the brain injury appears to be. They help care teams plan treatment and speak clearly with one another.
The group is based on the score, but it is rarely read alone. Clinicians also look at brain imaging, such as scans, and at how the patient changes over time. A score taken in the emergency room may look very different from one taken a few hours later.
Clinicians describe each group in neutral, medical terms. A severity label describes the injury at that point in care. It does not predict how a person will recover, and it does not tell a family what the future will hold.
Why a Score Can Change and Why Timing Matters
GCS scores are often recorded more than once. The first reading may differ from later readings. A person may become more alert, or they may become less responsive as swelling or other changes develop.
Other factors can also affect a reading. Sedation, medicine and other medical treatment can change how a person responds when a score is taken. Clinicians read each number in that context.
Doctors watch trends over the hours and days after a crash. A pattern of change often tells the care team more than any single reading. Each score is written into the medical record, and those records are a central part of how a brain injury is described later.
What a GCS Score Does Not Tell You
A GCS score measures responsiveness at the time of testing. It does not measure memory, thinking, mood or other effects that may last. Those areas need their own evaluation over time.
A higher score does not rule out a brain injury. Some symptoms of a mild injury can appear after the first exam. People who notice changes in how they think, sleep, feel or behave should tell their medical providers.
Because of this, a single score is a starting point. It is one clue about the injury, and it leaves many questions open.
How Brain Injury Classification Fits Into a Crash Claim
A severity label is one piece of medical evidence. Other evidence includes imaging, treatment records and symptoms documented over time. Taken together, these records describe the injury more fully than one score.
A label such as mild, moderate or severe does not decide a legal claim by itself. The facts of each crash and each injury matter.
Timing is also part of the picture. Virginia generally allows two years from the date of injury to file a personal injury lawsuit (Va. Code § 8.01-243(A)); the clock runs from the date of injury, not the date of discovery, with narrow exceptions. Under Va. Code § 8.01-243, unless otherwise provided in that section or by other statute, every action for personal injuries, whatever the theory of recovery, shall be brought within two years after the cause of action accrues.
Federal rules also describe drug and alcohol testing for commercial driver’s license drivers, including some post-accident testing. Families in Richmond and Henrico County can read more about brain injury after a crash in Richmond and in Henrico County.

Common Questions About GCS After a Crash
What is the Glasgow Coma Scale for TBI?
It is a bedside score of eye opening, verbal response and motor response. Clinicians use it to describe how alert a person is after a head injury.
Can you have a TBI with a GCS of 15?
A high score does not rule out a brain injury. Symptoms can still appear and should be checked by a medical provider.
How long does a coma last after a brain injury?
The scale measures responsiveness at the time of testing. How long a change in responsiveness lasts depends on the injury, and the medical team tracks it in the record.
Does a GCS score decide who is at fault in a crash?
No. The score describes the medical condition only. Fault is a separate question that depends on the facts of the crash.
