ALR(Administrative License Revocation)
A Program to suspend the driving license Of Drivers Which are found driving carelessly under dwi(driving while intoxicated).You need a proper class if you are driving in USA
And know nothing about it. I will teach you all one by one.
Your license can be cancelled if:
a) You Refuse to give test necessary for determining weather you are intoxicated or not.
b) You Allow for test but your blood alcohol content is found greater than 0.8.
Note That This program covers over 41 states and This program is administrated by the Texas Department of Public Safety (DPS).
And believe me , ALR is not the only thing that you are going to face.
Actually DWI Initiates two things:
1) Criminal case,
2) ALR also known as Administrative License cancellation,

Someone should know how ALR works.
If a Law enforcement officer believes during traffic a reasonable cause for stopping driver then
1) First officer need to tell him his rights. These rights are:
a) Anything you tell us can be used against you.
b) You can arrange a lawyer during interrogation.
c) You have the right to legal counsel.
d) You have a right to remain silent.
After all these nonsense field sobriety tests. If Tests fails Then driver can be arrested and imported to Police station where Requested To give Breath Test ( Breathalyzer ) or blood test. Ideal concept but know,
How ideal this world is. If he denies then officer confiscates his driving license and determines suspension period.
Adult Refusal: 3 Month- 2 years
Adult Failure: 3 Month - 1 year
Minor DUI: 2 Month - 3 Month
And then conducts further procedure.(Obviously nothing good for you).

But what to do if nothing worked. But you don't need to worry. In Case, license is suspended then a temporary license can be issued for some certain routes (Such as office to home root), known as hardship license.
You Have 15 days for requesting Administrative License Revocation Hearing.
DWI Checkpoints are devils for careless drivers. law enforcement agencies selects some points on roadside( or on highways ) and detects suspected persons for DWI. These points are known as DWI checkpoints.
But all that is later. If your lawyer is not good enough then nothing will work. How will you know who is the best. Just because somebody charging you a lot. That should not be your algorithm. Please Check:
1) Lawyer past record, how many dwi cases he has handled and what is his success record.
2) Lawyer is a specialist of dwi or handles all types of cases,
3) Financial settlement, what is the cost of lawyer.
4) Does lawyer has his own Intoxilizer 5000 breath machine and he is well familiar with it.
5) Is law familiar with Standardized Field Sobriety Tests.
6) dwi attorney self confidence, can he satisfy you.

Field Sobriety Test can be performed on you .They are for on the spot determination of weather driver is drunk or not. These tests were developed by the National Highway Traffic Safety Administration (NHTSA).
These are:
A) The horizontal gaze nystagmus (HGN):
if the eye cannot follow a moving object smoothly.
B) The walk-and-turn,
Listen and follow instructions during physical movements.
C) The one-leg stand.
