At 30 mph, you should generally be in 3rd gear for good control and responsiveness in a manual car, allowing for easy acceleration or slowing without constant shifting; however, 4th gear can work on quiet, flat roads, while 2nd gear might be better for areas with parked cars or bumps. The ideal gear depends on your specific car, engine, and road conditions, but 3rd gear offers a great balance for typical 30 mph zones.
If you are going 20mph, in most cars, you are at the top of gear two or bottom of gear one. Choose/stay in gear two if your speed will be fluctuating below 20mph. Choose/stay in gear three if your speed will be going above 20mph.
There is no 'hard-and-fast' rule for using 4th gear, as it depends on road speed relative to engine revs and road conditions. (Including traffic, road layout, perceived hazards and how much weight in the car).
As a driver when there is no need to accelerate, the overdrive function should be turned off. Also, when driving up a hill or downhill, the overdrive function may lose its effectiveness. When shifting to a lower gear, turn the overdrive feature off.
In automatic transmissions, the overdrive (O/D) function allows the car to maintain higher speeds while keeping the engine's revolutions per minute (RPM) low, improving fuel efficiency and reducing engine strain.
Under any normal driving conditions, like on freeways or highways, you should use the standard D gear. Using the D3 gear on the highway is not recommended or safe. Ideally, D3 should only be used for gaining uphill speeds during heavy traffic (stop-and-go situations).
Now Let's Move on to the Numbers!
So, what do they mean? 1 & 2: These two gears are typically lower and used when driving at a slower speed. 3 & 4: These two gears are typically higher gears used when driving at a faster speed. 5: This gear is also high but is mainly used for highway driving.
Let's break it down: In many standard passenger vehicles, fourth gear often kicks in around 30-40 mph (48-64 km/h) and allows for smooth acceleration up to about 70 mph (112 km/h).
When to Use Third Gear. Good for speeds of up to 30 mph. While second gear is generally good for speeds of up to 20 mph, in some cars you may feel a strain if you try and drive in second gear past 16 mph or so. In such cases, third gear is a lot more comfortable and a lot more efficient.
In most vehicles equipped with a manual transmission or an automatic that features a low range (often labeled as 'L' or '4L'), you can typically expect speeds ranging from 5 to 20 miles per hour (8 to 32 kilometers per hour). This may sound slow compared to highway driving but remember: it's all about control.
Yes it is recommended that in a modern manual transmission you can skip gears when going up or down. For example; when accelerating you can if required change-up from 1st to 3rd, though 3rd gear may labour due to low engine revs.
31 mph in a 20 mph area. 42 mph in a 30 mph area. 53 mph in a 40 mph area. 64 mph in a 50 mph area.
Perfectly flat road, 35 mph constant speed would be fine in 5th. Relatively flat road at 40+ mph (1500 rpm) is also fine in 5th. Relatively flat at 1300 rpm (35 mph) is questionable as to whether 4th or 5th is more economical.
On automatics with electronic shifters, shifting between D ↔ N at speed can trigger warnings or wear clutch packs. In an emergency, you can't accelerate out of trouble — your car just rolls.
Third gear is a very flexible gear in modern cars, including diesel cars, and it's the ideal gear when you need to keep your speed to 30mph or under. The IAM has a simple maxim. 'Get the correct speed for the hazard – then get the correct gear for the speed'. At 30mph that gear should always be no higher than third!
Can I switch from 4WD to 4WD High while driving? Yes, as long as you are within the recommended speed range (typically 5-55 mph).
It shows the order of the gear and allows you to select the one you need by moving the shift lever up or down. The majority of motorbikes today have a shift pattern of 1-N-2-3-4-5. This implies you move the shift lever down for first gear and up for higher gears.
It's best to use D3 when driving uphill, downhill, in stop-and-go traffic, and on slippery roads. Don't use D3 during highway driving and towing. You should also avoid driving faster than 30 mph when using D3. Not all automatic transmission cars have D3.

The 9HP is the world's first 9-speed automatic transmission for passenger cars. Land Rover and Jeep launched it at the 2013 Geneva Motor Show. The 2014 Jeep Cherokee then was the first car with this transmission delivered to customers.
Towing Speeds and Gears
D3 is the proper shift lever position to use when towing a trailer in hilly terrain. (See "Driving on Hills" in the following column for additional gear information.)
S mode or sport mode is a mode where the engine runs at a higher revolution than D mode, increasing the car's acceleration. The increased acceleration will make you feel more fun to drive and more agile.
AWD can be used on pavement with no ill effect because it is engineered to enable each tire to rotate at its own speed in turns—inboard tires rotate slower in corners. This makes AWD a better system than 4WD for the average driver seeking bad-weather security.
