	Engage the Parking Brake when Parking a Vehicle *Lawrence Livermore National Security, LLC 
	
Statement of Lessons Learned 
Whether government-owned or personal, a vehicle is not properly parked 
until:

�the engine is turned off,
�the automatic transmission is in park (or the manual transmission is in 
gear),
�the wheels are aligned correctly (turned in the correct direction if 
parked on a slope), and
�the parking brake is engaged. 
Discussion of Activities 
A driver stopped a vehicle in a designated parking space, exited, and 
proceeded to engage in conversation with a co-worker. Shortly after, the 
driver and co-worker suspected that the engine might still be running. 
The co-worker moved from in front of the vehicle to the passenger side 
to listen for engine noise. The driver moved to the driver�s side, 
opened the door, placing his right hand on the driver�s seat.He leaned 
into the cab to check the engine status when the vehicle suddenly 
lurched forward, jumped the parking stop, rolled across the walkway 
(where the driver and co-worker had been standing a moment earlier), and 
collided with the building on the other side. 
Analysis 
The driver thought he had put the transmission in park and had turned 
off the engine before exiting the vehicle; however the parking brake had 
not been engaged.The driver was familiar with the vehicle and had driven 
it regularly over the previous 18 months.

The vehicle was equipped with an engine-alert system; however, noise 
from a nearby dump truck prevented the driver from hearing the single 
chime that sounds to warn that the engine is still running when the 
driver�s side door is open.

The driver did not recall whether the front tire was actually against 
the parking stop when he exited; however, the height and configuration 
of the parking stop is not designed to act as a brake. An experiment 
with a minivan and a similar parking stop configuration confirmed that a 
vehicle that is in gear, with the engine idling, could roll over the top 
of this type of stop configuration if the front tire is more than a foot 
from the stop when it starts moving.

The walkway was not raised so after the vehicle rolled over the stop, 
there was nothing to prevent its continual motion. 
Recommended Actions 
The driver was treated at the on-site medical facility for cuts and 
abrasions after being knocked to the ground. His co-worker was not injured.

Review vehicle parking protocol with all employees authorized to operate 
government vehicles at LLNL.These includes:
Parking:Park only in designated parking spaces.Turn the front wheels so 
the vehicle will not roll into traffic but rather contact the curb and 
stop after traveling the shortest distance possible.

-Transmission: Verify that the automatic transmission is in Park, or the 
manual transmission is in gear. (First gear is recommended if the 
vehicle is facing upslope; reverse if the vehicle is facing downslope).

-Parking Brake: Engage the parking break when the vehicle is parked or 
standing unattended. This applies when parking on level surfaces as well 
as sloped.

-Engine off: Look at the instrument panel, dashboard lights or other 
visual indicators that engage or illuminate when the engine is running 
or the ignition is in any mode other than off. This is especially 
important for electric or hybrid vehicles because there will be 
little/no engine noise.

-Seat Belt: Remove your seat belt and exit the vehicle. Listen for 
warning sounds that indicate the engine is not turned off. 
JLab Preventive Measures 
JLab's Vehicle & Motor Equipment Policy and Procedures, Section 2.2, requires individuals operating vehicles as a representative of Jefferson Lab possess a valid driver's license issued from within the United States.  Section 2.3 also requires vehicle operators to complete the GEN 400 training course, "Local Driving Conditions for Jefferson Lab Workers".  This training contains provisions that require when vehicles are left unattended, their motors be turned off, and that parking brakes/chocks be used as appropriate.
